How can I manually uninstall .NET Framework Beta 2?

Question

Uninstalled VS2010 Beta 2. Uninstalled .NET Framework 4 Extended Beta 2.

On attempting to uninstall .NET Framework 4 Client Profile Beta 2. I get

Blocking Issues: You must uninstall the .NET Framework 4 Extended Beta 2 before you uninstall the .NET Framework 4 Client Profile Beta 2.

On attempting to reinstall Framework 4 Beta 2 I get:

Answer 2

I just did this the other day. I used "Uninstall Programs" (formerly "Add/Remove Programs") in Control Panel to remove everything that had "beta 2" in the name.

Answer 3

In addition to removing all keys under: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4 I had to also remove this key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4.0 After doing this, the uninstaller for client profile beta 2 no longer complains.
