Visual Studio 2005 won't install on Windows 7

My question relates very closely to this question: How do I bypass Visual Studio 2005 SP1 failing to install on Windows 7?

However this question hasn't provided the answer I'm looking for. I'm trying to install Visual Studio 2005 onto a clean Windows 7 (64 bit) box. However I keep getting the following error when the 'Microsoft Visual Studio 2005' component finishes installing ...

Error 1935.An error occurred during the installation of assembly 'policy.8.0.Microsoft.VC80.OpenMP,type="win32-policy",version="8.0.50727.42",publicKeyToken="1fc8b3b9a1e18e3b",processorArchitecture="x86",Please refer to Help and Support for more information. HRESULT: 0x80073712.

On my first attempt to install VS 2005 I got a warning about compatibility issues. I stopped at this point, downloaded the necessary service packs and restarted the installation from the beginning. Every since then I just get the error message above. I keep rolling back the installation and trying again ... it's but always the same error.

Any help would be very much appreciated.

Thanks.

I'm pretty sure this error message indicates the component store has been corrupted. You could take a look at this article: http://support.microsoft.com/?kbid=947821
