Each of the .NET Frameworks (.NET 2.0, .NET 3.0 .NET 3.5 and .NET 4.0) comes with their concomitant directory of Tools. For example, if a user downloads the current Windows SDK version 7.1; it comes with two versions of clrver. There is one for .NET 3.5 Framework and another for the .NET 4.0 Framework. You would find them respectively in the following directories depending on your installation directory a. C:\Program Files\Microsoft SDKs\Windows\v7.1\bin\ b. C:\Program Files\Microsoft SDKs\Windows\v7.1\bin\NETFX 4.0 Tools So in your case, for VS2010, you were seeing the clrver from the following directory c. C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools SpamBlazer Technologies abc @Jaap Trouwborst

On my development machine running Windows Vista and all .NET frameworks above v2.0 installed, this command only returns that v2.05727 is installed... Can you explain this? Ah, when I try this command using the VS2010 command prompt, it did also return that .NET 4.0 is installed. Well, I just tried it.
