You can remove any NET versions, using Dotnetfx Cleanup Tool , then reinstall whatever version you may require.
Thanks. Unfortunately looking through the readme file that comes with the cleaner it appears it will not remove certain versions, depending on OS.
I am waiting for holdem manager support to get back to me to advise which version there software actually uses.
I use windows vista home.
From the readme file ....
Not all of the above products will appear in the UI for the .NET Framework cleanup tool on every operating system.The cleanup tool contains logic so that if it is run on an OS version that includes the .NET Framework as an OS
component, it will not offer the option to clean it up
. This means that running the cleanup tool on Windows XP
Media Center Edition or Tablet PC Edition will not offer the option to clean up the .NET Framework 1.0, running
it on Windows Server 2003 will not offer the option to clean up the .NET Framework 1.1 and running it on Windows
Vista or Windows Server 2008 will not offer the option to clean up the .NET Framework 2.0 or the .NET Framework 3.0
I had already tried this cleaner as recomended on the holdem manager forum, and there rep when controlling my machine via teamviewer tried the same procedure to no avail
