I am unable to install the new .NET Framework 2.0 SDK. On two different machines. I keep getting the error :

Error creating process <C:\DOCUM~1\steve\LOCALS~1\Temp\IXP000.TMP\Install.exe>. Reason: C:Windows\system32\advpack.dll

I have all the latest patches to the operating system(XP) on both machines and I have installed .NET Framework
Resdistribution pack.

Any idea what I am doing wrong?

Thanks,
Steve
