You should leave .NET 1.0 and 1.1 installed.
Go to
www.snapfiles.com and download the tool 'Advanced Unistaller Pro 2005'.
This is a 30 day trial version. It has a registry cleaner feature that
should find and
correct the 'missing file' problem.
I contacted MS support on this issue and we are working on it. Basically there
seems to be a relationship with .NET Framework 2.0 and Windows Installer V
3.1.
The executive summary statement is the Windows Installer is a pretty poor
component. It does not show key installation details, current installation
status (for
corruptted installations). It also has not feature to 'clean' the
installation environment of corrupted problems.
The .NET Framework 2.0 install/update had a problem and introduced some
corruption (we suspect but can not validate). We ended up going to
www.snapfiles.com and downloading several registry cleaners and uninstall
products to fix up the install environment.
Currently there is some SQL 2005 beta residue that we can not remove from
the system. This is preventing the install of SQL 2005 release version.
Will post outcome of this effort when complete.
