Best way to install a Netgear FR114P Print Server (and possibly others) under Windows XP

I'm adding this posting just so it might help others in my plight and save them some trouble.

UPDATE (27 April 2007):
It just occurred to me, after seeing the number of hits on this post, that the technique described below (LPR) for installing print servers goes beyond the specific Netgear model discussed. So it's quite possible that this tip would be useful for installing just about any print server under Windows XP (and maybe under Windows Vista too, although I haven't tested the latter).

- - - - -
For a couple of years I've been using (under Windows XP) a Netgear FR114P Pro Safe™ VPN Firewall w/4 Port 10/100 Switch and Print Server to support an older but still quite adequate laser printer that only has a parallel printer port -- no USB or Ethernet connection like many of the newer printers.

The set-up procedure that I always used previously, without any major problems, involves setting up a "Netgear Printer Port Driver" using the supplied Windows installer. However this time, for my brand-new dual core desktop system, no matter how many times I tried the procedure using all variations that I could come up with, the required printer port never appeared. Naturally enough, this in turn meant that the Windows XP "Add Printer" procedure didn't have any way to install the printer.

The set-up procedure had worked well enough in the past, but I had no idea at all why it failed miserably this time: there were no diagnostics, and no method for troubleshooting the problem.

After spending much of yesterday afternoon tearing my hair out, I decided to give up on the provided installer and start searching the forums and knowledge bases for a workaround.

Luckily, in a rather obscure forum I came across a hint that led me to the reference manual for the newer Netgear Pro Safe Wireless 802.11g Firewall/Print Server Model FR114P. It contained the vital extra information that was not in the older FR114P manual:

  • For Windows XP and 2000 only: use TCP/IP Line Printer Remote (LPR)
    printing, rather than installing the Netgear Printer Port Driver.
  • No printer port software needs to be installed.
  • Windows XP or 2000 users can print directly to the print server router. Print jobs are spooled (queued) on each computer. The computer sends the print job directly to the LAN IP address of the FR114P [not via a printer port].
It seems that the "printer port" approach is really meant for the older Windows operating systems (Windows 95/98/ME/NT4) and the TCP/IP Line Printer Remote (LPR) protocol is a superior way to set it up for Windows XP.

I have extracted the relevant chapter and posted it for you at FR114P Print Server Installation for Windows XP (also at FR114P Print Server Installation for Windows XP ) and I hope it saves you some time and stress if you come up against the same problem!

IE7 browser share at (mid-January 2007)

Continuing my regular series of posts on browser share for visits to (and to its mirror site). Over the last month and especially during the last week or two, there seems to have been a decrease in Firefox share from 20-25% daily to 15-20% daily.

The Firefox drop-off has been taken up by Internet Explorer 7 with the total for IE6 plus IE7 now having built up from around 70% daily to nearly 80% as shown in today's pie chart:

And over at Microsoft's IE Blog we have Group Manager Tony Chor proclaiming:
I’m pleased to report that on January 8th, we had the 100 millionth IE7
installation. However, even more important than installations is usage. According to WebSideStory (the company we use to measure browser usage), as of this week, over 25% of all visitors to websites in the US were using IE7, making IE7 the second most used browser after IE6. We expect these numbers to continue to rise as we complete our final localized versions, scale up AU distribution, and with the consumer availability of Windows Vista on January 30, 2007.
I presume that when he refers here to "AU" he means "Automatic Updates" (or the like) and not Australia!

APopLectic about APL?

Conway's Game of Life in one line of APL
APL, now there's a programming language! None of this verbose stuff, such as Java or C# or VB .NET with their hundreds of lines of code thousands upon thousands of classes and interfaces. Just a small number of special symbols to learn, and you can solve all the problems of the known universe with APL ...

Some people get quite upset, even enraged, about using APL as a "data processing" and I can understand that, but I'm not one of them. Nor am I an APL practitioner, just an admirer.

David Yee, fellow ex-IBMer down here in Melbourne (Australia) in the "good old days" during the 1970s/1980s used to be a devotee of APL, and wrote some amazing programs. I well remember a Solitaire game that he coded in just a few lines of APL.

These thoughts flooded back to me when I read Jonathan Erickson's recent editorial over at Dr Dobb's Portal: APLs and Oranges

And this led me to take a glance at Michael Gertelman's Conway's Game of Life in one line of APL which will give you a feel for the language if you've never been exposed to it before. Here's the code, again:

Read Michael's article to understand what this code is doing and thereby get a feel for the power of APL.

Steps for installing multiple Lotus Notes Client releases on a single system

(Last updated 08 April, 2008)

So, you're perhaps a developer or a tester or administrator, and are wondering how you go about installing more than one Lotus Notes Client release on your computer.

In October last year (2006) I briefly discussed some tips for installing multiple Notes client releases on a single system with some links to other peoples' posts on this topic.

There was also a related post about the possibility of using Junction Points or SoftGrid for Installing multiple Lotus Notes releases on a single system? but, in retrospect, I don't think that this is a useful path to follow. Indeed, it could be an extremely difficult and messy way to go about installing multiple Notes/Domino releases!

The most "generic" solution is to run multiple virtual machines on the one system, each VM having a different Notes/Domino release. This is, of course, nearest to running them on separate systems, but it doesn't work too well if your system lacks processing power, especially RAM. It's the cleanest solution, in the sense that each Notes/Domino release has its own separate Windows registry to play with (no chance of OLE/ActiveX conflicts).

Since mid-2003 I've been using two different notebook PCs as my main development platforms, but they were not expandable enough in terms of processor power, RAM and hard disk to cope with what I was trying to throw at them. For example, they both happened to be limited to 1GB of RAM. By limiting the separate VMs to no more than about 128 Mb of RAM each, and with the aid of some external USB-attached hard disks, I was able to run three or four virtual machines per notebook. However the performance was a little on the sluggish side, okay for testing purposes but certainly not for continued use.

With the above in mind, over the Christmas/New Year break I've taken delivery of a brand spanking new desktop system: an AMD Athlon X Dual Core 5200+ processor, with 4 GB of RAM and around 1 TB of mirrored hard disk. I pressured hardware specialist Gordon Newell (friend and fellow ex-IBMer) of Chalcot Micro Systems (here in Melbourne, Australia) to build me an ultra-fast yet ultra-quiet desktop machine (it's turned out to be quieter than my latest notebook PC, so I can enjoy listening to quiet music without annoying fan and disk drive noise). Altogether, it should keep me happy for a couple of months, before I notice that it's not fast enough! I'll certainly be running several virtual machines, but it's a pity that the 32-bit Windows XP version cannot make full use of the 4GB of RAM for applications, reporting only about 3.GB as being available. (I would have used the 64-bit version to overcome this issue, however lack of sufficient drivers prevented me from doing so. And this is not to mention the sad and sorry story about having to purchase 64-bit versions of all my applications, but don't get me started on that!)

Here now is a more explicit description than last time about installing multiple releases of Notes/Domino on a single system. Note that this enables you to run each release, but not necessarily concurrently. This is adequate for my purposes but might not be for yours, in which case either follow the VM path or see if Bill Buchan's tips work for you (these are referenced in my earlier post).

The scenario is that I install everything on the Windows G: drive -- which for historical notebook-PC-related reasons happens to be a logical rather than physical drive, though this does not in any way affect the outcome. Change the drive letters to suit your own situation (and, of course, they don't all have to be installed on the same drive).

I'm assuming here that, for development and support purposes, your intent is to install not the simple Notes Client but rather the Domino Designer/Administrator product.

The releases should be installed in the following sequence, meaning that when you're finished the Windows registry should have that latest Notes/Domino settings in effect (in this example, Notes 7.0.2):
  1. Notes plus Domino R4.6.4 were both installed into the G:\Notes4 folder (it could have been separate folders, but this works for me, and anyhow I hope that there aren't any of my customers still using R4.6.4).
  2. Notes R5.0.11 was installed into the G:\Notes5 folder, and Domino R5.0.11 was installed into the G:\Domino5 folder.
  3. Notes R6.5.5 was installed into the G:\Notes6 folder, and Domino R6.5.5 was installed into the G:\Domino6 folder.
  4. Notes R7.0.2 was installed into the G:\Notes7 folder, and Domino R7.0.2 was installed into the G:\Domino7 folder.
(Stating the obvious, when you're doing this for yourself you would use your own directory names.)

The release installations go on pretty much uneventfully until you get to the final stage, installing R7 after you have installed R6. The first consideration arises because IBM enhanced R6 to support roaming Notes Client users, see IBM Technote 1106932: Is a Multi-user Installation of Notes/Domino 6.x Needed in Order for Users to Roam?

As a consequence of having taken the multi-user path in an earlier installation, you may need to use the registry tweak described in IBM Technote 1176213: Error: 'You are attempting to upgrade a multi-user installation' when upgrading to a single-user install -- and might find helpful information in Technote 1113003: Unable to upgrade Single-user install to a 6.x Multi-user install plus Technote 1114371: Where is the option for a Multi-user Install of the Notes Client? and perhaps also Technote 1219467: Users are prompted to complete the Client Setup Wizard after upgrading a Notes multi-user installation to 7.0

In my case, I wanted to install Domino Designer/Administrator R7 into the Notes7 folder, but instead was presented with the following installer panel (click on any of the following the images to see an enlargement):

The problem here is that you don't want to install R7 into your R6 folders, but the installer has the Change... buttons grayed out so you are stymied by being prevented from selecting different folders for R7. So what do you do next?

Well, my workaround was to cancel the above R7 installation, start the Windows registry editor (regedit.exe) and locate the hive key HKEY_LOCAL_MACHINE\SOFTWARE\Lotus\Notes whereupon I could see entries for R5 and R6 (but not for R4, which is possibly why you can get away with putting both R4 Domino and R4 Designer into the same folder). I renamed them by adding the string _OLD to their names, like this:

Then, I renamed the Notes6 folder to Notes6_OLD.

Having done that, I relaunched the R7 Domino Designer/Administrator installer and this time was allowed to select the desired new R7 target folders, thus:

When the R7 install was complete, I refreshed the registry editor window and got:

The final step is to rename the R5 and R6 hive key entries back to their proper values (by removing the string _OLD from their names), thus:

And of course, I renamed the Notes6_OLD folder back to Notes6.

After that, all four Notes/Domino releases more or less operated normally.

I run one server and one designer client at a time, and they don't necessarily have to be at the same release level. For example, I might leave the Domino 7.0.2 server running continuously and launch the various Notes Client releases one at a time to perform function compatibility tests.

It's likely that certain Windows registry-based functions such as OLE will only work for the last-installed version, but you can't have everything! (If this is an issue for you, then try the Virtual Machine approach, where you have the older releases each running in its own VM with its own dedicated Windows registry settings.)

UPDATE - 05 May 2007:
I just came across IBM Technote 1233184 (modified 2007-01-02) which more or less confirms that my suggested procedure works. The body of this Technote is as follows:

Coexistence of Notes 6.x and 7.x on a single workstation

IBM Lotus recommends that you do not install more than one version of Notes on the same computer. Notes is not designed to function in this manner. Rather than install, for instance, Notes 6.x and Notes 5.x on the same machine, upgrade your Notes 5.x client to Notes 6.x. If you install both versions on the same machine, be aware that this installation could have adverse effects on the operation of the version of the client (or server) that was originally installed. For example, OLE/COM settings will point to the Notes 7.x directory, default email client settings, etc.

With that understanding, follow the steps below to install Notes 7.x on a machine that also has 6.x installed:Note: You must have local administrator privileges to complete this procedure. These instructions apply to single user installs only: they do not apply to multi-user client installs.

Shut down the Notes client and all Notes-related tools, utilities and add-ins running on your computer.

Rename the Notes 6.x directory. Notes 6.x is typically installed to \Program Files\Lotus\Notes on Windows. For example, you could rename the directory "Notes6."

Rename the entire Notes registry key HKEY_LOCAL_MACHINE\Software\Lotus\Notes. For
example, you can rename it HKEY_LOCAL_MACHINE\Software\Lotus\Notes6

Rename the entire Installer registry key KEY_CURRENT_USER\Software\Lotus\Notes\Installer.

For example, you can rename it

Run the Notes 7.x install program (SETUP.EXE). Select new locations for the program and data
directories. For example, you can select \Program Files\Lotus\Notes7 and \Program Files\Lotus\Notes7\Data

During the install you may see an error message

"Error 1905.Module c:\program files\lotus\notes\nelsons.Dall failed to unregister. RESULT". Click OK and installation will proceed.

When the install program has finished, rename the 6.x directory back to the original directory name, for example, \Program Files\Lotus\Notes)Note: The information provided above is taken from the Notes 7.0 Release Notes.

Parallelinstallation Von Clients, merer Detentions

Here's a translation from German to English (performed by Google Translate):

UPDATE - 22 January 2008:
My website and blog tracking services show that Notes/Domino developers all around the world are very interested in this topic, so here's another promising tip.

I've recently come across another product that appears to have the potential for supporting multiple Lotus Notes Client releases -- or for that matter most other Windows software -- concurrently and robustly. It's called Altiris Software Virtualization Solution (SVS), now a Symantec product. There's a full-fledged professional commercial version and a free personal version (the same as the regular commercial product except for the server-side components for centralized management).The personal version should be good enough for the solo Notes/Domino developer. You can read about SVS at I get enough time I will read the rather hefty documentation and give SVS a try, then report the results in this blog.

UPDATE - 12 March 2008:
Over at his BizzyBee's Thoughts blog, Martin Vereecken has an article Notes 8 and Notes 7 coexistence that gives another take on the Windows registry settings that I discussed earlier on in this post.

But the most precise recipe so far is this one by Thomas Bahn: Installing and running Notes R5, 6, 7 and 8 concurrently ... Nice work, Thomas!
