Failed to install/uninstall Async CTP on windows XP machine

Question

I've run the installation of Async CTP on Windows XP machine, though i do not see any effect. Nither on VS2010pro C# compiler nor on installed programs list.

That would not bother me much, but installing MVC3 RC2 failes since its incompatible with Async CTP.

I've found no way to overcome the problem. For some reason Async CTP does not install correctly, and thus cant be uninstalled.

Any help would be appreciated!

Answer 1

From the "Uninstall Instructions.rtf":

The Microsoft Visual Studio Async CTP is installed as two updates:

1) .NET Framework 4.0 update called ".NET Framework Async CTP"
2) Microsoft Visual Studio 2010 update called "Microsoft Visual Studio Async CTP"

To uninstall go to Control Panel -> Programs and Features -> View installed updates. You will need to uninstall both updates.

Answer 2

Under XP on the "Add remove programs" dialog check in the "Show updates" checkbox. You should see the updates in the list.

Answer 3

The solution was found searching in the registry.
