Cannot install Virtual PC on Windows 7

Hello,

I'm running Windows 7 RC (Windows 6.1 Build 7100) 32 bit. My computer
hardware supports virtualization, and it's enabled in BIOS.

When I try to install Virtual PC from this site:
http://www.microsoft.com/windows/virtual-pc/, file Windows6.1-KB958559-x86,
I'm always getting a message:

The update is not applicable to your computer

What could be wrong here?

I would appreciate your help.

Thank you,

Peter

 

As stated the Windows7 Virtual PC *requires* built-in CPU VT
technology enabled in the BIOS on the host machine. If you don't have
the required hardware then it can't be installed. End of story.

Your only option in this case is to install Virtual PC 2007, which
will work even though it is not "supported".
Supported in this context means if you are eligible to phone Microsoft
for help on the system or not. It still works perfectly well.

And of course you can go elsewhere for a working virtualization
product:
VMWare Workstation, Player and Server
SUN VirtualBox

He says his hardware supports VT and it is enabled, and he wouldn't get
this error for that problem...

To the original poster, What version of Windows 7 do you have and are you
sure its 32-bit? You also say build 7100, that's not the released version
of Windows 7. (it's 7600)

 

Right, I misread it as NOT enabled in BIOS...

He is running a release candidate, maybe he then also must use the VPC
beta instead of the release?

I know I tested the W7 RC back before summer and then there was only
the VPC beta available. But that installed fine in the RC and worked
as expected.
I don't think it is wise to mix RC and beta code, and right now when
Win7 has hit the shops the OP should use the RTM and the VPC released
version.

 

Thank you for your response.

It is build 7100 for RC. According to this article:

http://www.jasonslater.co.uk/2009/06/11/windows-7-installing-windows-xp-mode/

Beta is 7000 and does not support Virtual PC.

Yes, virtualization is enabled in BIOS. I don't know if something else is
required, but I do know that in the past I was running Virtual PC on my
machine. I don't remember what version it was, but it was after 2007, I
bought my PC in 2008.

I wonder - if I install an older version of Virtual PC - will it work with
Windows XP mode? I guess I have to try.

I would buy the full version of Windows Ultimate, sooner or later I'll have
to do it anyway, but I'm not sure is it will work either.

Thanks,

Peter

 

It certainly appears the *released* version of XP Mode support
(confusingly named Virtual PC and installed as an update [KB958559])
checks that you are trying to install it on a *released* version of
Windows 7.

From the article and from other respondents here, it appears:

build 7000 = beta version
build 7100 = release candidate (RC) version
build 7600 = *released* (RTM) version

According to http://preview.tinyurl.com/m88r9f, build 7600 is the RTM
(released to manufacturing) version.

You mentioned the article but that article mentions *beta* for build
7000. It also mentions 7100 is the *RC* version. Plus it appears you
already knew you were using an RC version of Windows 7. Looks like
you're stuck using VirtualPC 2007 until you get the RTM version (build
7600) of Windows 7.

 

Thank you, I guess I need to buy a full version.

Peter

 

Installed the final version - everything is OK now.

Thank you for your suggestions.
