2.0 that are caused by registry permission problems ★★★★★★★★★★★★★★★ Aaron StebnerAugust 9, 200517 0 0 0 I have had a few customers report problems installing the .NET Framework 2.0 with the following symptoms: .NET Framework 2.0 setup fails and rolls back with no specific error message, just a generic "setup failed" message at the end The action that fails is "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50215\regtlibv12.exe" "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50215\mscoree.tlb" or "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50215\regtlibv12.exe" "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50215\mscorlib.tlb" (you can find the error by using the steps described here) The error code listed in the log file %temp%\dd_netfx20msi*.txt is 8002801c Examples of this problem are the comments locatedhere and here, and the Product Feedback Center bugs locatedhere and here and here. The underlying problem is that the Administrators group somehow was only granted read permission to some of the registry keys under HKEY_CLASSES_ROOT on these machines. When the .NET Framework setup tries to register type libraries, it needs to create some new values under HKCR and it fails because of a lack of permissions (8002801c means "error accessing the OLE registry"). I have been able to confirm that this is the problem by having one of the customers use RegMon, but I haven't been able to figure out how the permissions got modified to be this way. Up until now I also haven't been able to figure out how to fully reset the permissions so that .NET Framework setup will work. Fortunately one of the customers who had this problem contacted us with a solution that worked for them, and I wanted to list it here in case others run into this same problem i
