>I recently bought a new Windows 7 64 bit computer and loaded Visual Studio 2010 on it. When I try to install MM .NET 4.0 for VS 2010 on it... It says it is successful but it is not. The MM option in the treeview does not show up when adding a new project or item.

Try this:

1. Close all instances of Visual Studio

2. Launch a Visual Studio Command Prompt (Start | All Programs | Microsoft Visual Studio 2010 | Visual Studio Tools | Visual Studio Command Prompt)

3. In the Command Prompt, type DEVENV /SETUP

After several minutes, the command prompt returns, then you should be able to go into Visual Studio 2010 and see the MM .NET templates.

Best Regards,
