Can't uninstall .Net Framework

Question

Hello,

Im having some trouble installing the latest version of Visual Studio .NET. I had a previous installation of 2002 .NET Beta 2 that i removed. The only component that I cannot uninstall is the .NET Framework (English) Full v1.0.2914 (i think this was installed with BETA 2 but not sure, as i had in total 3 .Net frameworks installed! 2 of which uninstalled without error). When i attempt to remove it the uninstaller complains that it cant read/write to the registry.

I found a registry key for the .NET framework with a GUID of {E15850ED-31E6-40f4-AB51-E9FC4CCB48D3} and tried to uninstall it with msiexec:

msiexec /x "{E15850ED-31E6-40f4-AB51-E9FC4CCB48D3}"

this says that it is not installed!

I've had a good look through the BETA 2 links on this board and cant find a solution,
any help would be well received!

Answer 1

I've just found some info on manually uninstalling .Net framework v1.0:
http://support.microsoft.com/default.aspx?scid=kb;en-us;824643

Following this advice i get to the running installer and looking for .NET framework, i cant find it although there are two msi packages installed with a comment field: "Visual Studio .NET Baseline - English RTL x86 enu" and i have two packages that were installed around the same time with the comment: "Contact: Your local Administrator".

I guess if i can reinstall that particular vesion of the framework then this might solve it, I'll try reinstalling 2002 BETA 2 then have another go at removing it!

Answer 2

Solved: I just got rid of the "Visual Studio .NET Baseline - English RTL x86 enu" packages and now the .NET 2005 intaller is running ok!

If in doubt hazard a guess!

Run this Microsoft tool to uninstall .Net Framework http://go.microsoft.com/fwlink/?LinkId=47598

Rename C:\WINDOWS\system32\mscoree.dll as mscoree_old.dll or whatever name you want. Otherwise, you may get Error 1935 when you reinstall .NET Framework 1.1.
