Question

I cannot install WSS 3.0 x64 on Win2K8 server, the error says "IIS is running in 32-bit emulation mode"

Asked by: techcity

We have a Windows 2008 Server x64, which is running a simple third party web application. This server is way too powerful, and we decided to put more use on it, so I installed WSS 3.0 w/SP1 on this server successfully a few days ago.

But yesterday the web app had a problem, and we suspected WSS 3.0 was the cause, so we removed WSS 3.0, but the problem was still there. We did lots troubleshooting, including reinstalled IIS, reinstalled the web app and finally we fixed it - the problem was nothing related to WSS 3.0, it was because a file of the web app was accidentally deleted.

However, When I tried to reinstall WSS 3.0 today, I got this error:
"Setup is unable to proceed due to the following error(s):
Internet Information Services is running in 32-bit emulation mode. Correct the issue(s) listed above and re-run setup"

I contacted the web app tech support again and asked them if and how I can make IIS back to 64bit mode. They did not answer my question except telling me that their software must be running in 32 bit mode.

I believe WSS 3.0 and the existing third party web app should be able to coexist on the same server, because I installed WSS 3.0 successfully at the very beginning. I think somehow IIS settings were messed up during the troubleshooting and prevented me from installing WSS 3.0 afterwards.

How can I make both WSS 3.0 and the 32-bit web app work on the same server then?
I am not an IIS expert at all, could someone please help?

Thanks in advance

Jack

Have you tried installing the 32 bit version of WSS? Not the bet option and I'm not sure it'll work. In reality I'd suggest moving the 3rd party application to a VM or something and reinstalling everything so you can use WSS as 64bit. Next version won't be 32bit so it would save you having to upgrade it later.

 

by: poortateyPosted on 2009-04-27 at 07:33:21ID: 24242092

Haha, I just ran into this one. You can enable and disable 32-bit emulation mode with this command (all on one line):

CSCRIPT %systemdrive%\inetpub\adminscripts\adsutil.vbs w3svc/apppools/Enable32BitAppOnWin64 0

The argument "zero" at the end of this command is important, as it turns 32-bit mode off.  You can run the same command with a "one" to turn it back on.

It will return the following text:

enable32bitapponwin64: (BOOLEAN) False

You might also need to re-register 64-bit ASP.NET.

  1. Change directory to C:\Windows\Microsoft.NET\Framework64\v2.0.50727 
  2. Run the command: ASPNET_REGIIS -i -enable 
  3. it will return the following text: Finished installing ASP.NET (2.0.50727) 

Note: you can switch back to 32-bit ASP.NET by changing directory to C:\Windows\Microsoft.NET\Framework\v2.0.50727 and running the same command.  But when I did this I got an error saying IIS wasn't installed.  I think you need to have IIS6 components installed for that to work.

Now, as to the question of whether these two apps (i.e. vendor solution and WSS x64) can co-exist on the same IIS instance, I can't say.  Give it a try, but if the vendor says they won't support their software if it's running in x64 mode, then you should believe them.  Always err on the side of supportability, especially if you are not, as you say, an IIS expert.

You might follow Steve_NJ's suggestion and simply use the 32-bit version of WSS, which would not block the installation if you're running in 32 bit emulation mode.

Poortatey

I am a bit afraid to run your command "CSCRIPT %systemdrive%\inetpub\adminscripts\adsutil.vbs w3svc/apppools/Enable32BitAppOnWin64 0"

If i run it, it will disable IIS 32bit,  will the third party web app still be okay?

thanks
jack

Hi Steve,

I have not tried WSS 32 bit yet, because according to MS web site, i have to install WSS 3.0/sp1 x64 on a Win2K8 server.

But i can definitely give it a try later.

If i am lucky to make WSS 32 bit work, will it be very slow compared with its 64 bit coountpart?

thanks
jack

Well, as with any piece of advice you receive from the internet, take all necessary precautions.  None of us have any idea what other factors are at play on your servers; only you do.  So if you want to try this, make sure you have a good backup just in case.

That said, I think it's easy enough to switch between 32-bit and 64-bit using the adsutil.vbs.  You might do some googling on ADSUtil if you're uncertain, but it's been around quite a while.

If you're too nervous to try it on a production server, why not build up a VM and test it there first?

 

by: poortateyPosted on 2009-04-27 at 08:16:27ID: 24242619

If the server is as underutilized as you say, WSS running in WOW64 mode should not have much lag.

Hi Poortatey,
I have run the script and successfully installed WSS 3.0 w/SP1 x64.

I opened  IIS Manager, clicked App Pools, I saw "Sharepoint Central Administration v3" is one of the listed items. However, the version of .NET Framework associated with it is "2.0", which I expected "3.0"

Is this a problem?

Thanks,

jack

 

by: poortateyPosted on 2009-04-30 at 06:11:13ID: 24269541

Nope!  Sharepoint is an asp.net 2.0 web app. It uses .net 3.0 for things like workflow and core services.

How is your other webapp running?

 

by: techcityPosted on 2009-04-30 at 07:50:24ID: 24270534

I did the install of WSS 3.0 yesterday afternoon, we briefly tested the third party web app okay
I re-registered 64-bit ASP.NET as you mentioned yesterday late night, I have not heard of anything from users yet. By the way, what's the purpose to re-register 64-bit ASP.NET?

Can you please check your IIS7 and see what version of .NET Framework is being associated with Sharepoing Central Administration 3?

MS Doc says that WSS 3.0 is a .NET Framework 3.0 application and .NET Framework 3.0 must be pre-installed, which i already did. I just would like to confirm if this is a problem before i proceed in further.

Thanks a lot and have a good day

The web app portion of sharepoint uses .net 2.0, and the WSS services use .net 3.0. They both need to be installed. I suggested reregistering 64bit asp.net in case that version had been set for your 3rd party webapp. But if everything is happynow I guess you're set.
