Hi - when I try to install the Tools for Visual Studio extension, I get an error saying it cannot be installed because:

"The extension 'Deployment Framework for BizTalk Tools for VS 2013' requires a version of the .NET Framework that is not installed."

What version is required? I have the following installed (on Windows 7):

2.0.50727.5420
3.0.30729.5420
3.5.30729.5420
4.0.0.0 (Client)
4.7.02053 (Full)

Thanks!
