I receive the error "Unable to find a version of the runtime to run this application." when trying to run MuvAudio2 after Windows Update installs the .NET Framework 4 Client Profile.

MuvAudio 2 requires the .NET Framework 2.0 and for some strange reason, even though .NET 2.0 is installed, when the .NET 4.0 Client Profile is installed, it makes MuvAudio 2 think that .NET 2.0 is not installed.

We have released an update to MuvAudio 2 that resolves the issue, which you can download here.  The latest version number (v2.9.9.0) remains the same but the installer is marked as rev2. This signifies that it is the 2nd revision of v2.9.9.0 that only includes the MuvAudio2.exe.config file that resolves the issue.

After installing this update you should now be able to run MuvAudio2 when the .NET Framework 4.0 Client Profile is installed.
