Visual Studio 2008 on Windows x64 Installation error

I am trying to install Visual Studio 2008 on a Windows 7 x64 machine and I am unable to install it and don't want to give up Windows 7.

Below is the error log.

[11/05/09,15:21:08] Microsoft Visual Studio 2008 64bit Prerequisites (x64): [2] e:\setup..\wcu\64bitprereq\x64\vs_bsln.exe could not be unpackaged because it is not a cabinet.

Is it possible that your installation-medium is corrupt? If you downloaded it, can you verify its checksum?

I had the exact same error while attempting to install VS2008 Professional on Windows Server 2008 R2 (64-bit). I tried clearing %TEMP%, completely uninstalling SQL Server 2008 R2 and all its shared components, but still no luck. I did a hash check on the SHA1 of the ISO I was using, which I had downloaded directly from MSDN. The SHA1's matched.

So FINALLY I went ahead and just downloaded another copy of the ISO, just for kicks. Well, it actually worked! Don't ask me why the first ISO never worked, as I said the SHA1 matched. But for some reason, the second time I downloaded the ISO, it worked.

Sorry I don't have a more rational solution, but it seems others on MSDN have had a similar success story.

this is due to any other version of VS is installed. uninstall any other version install it
