While the fully licensed version of Visual COBOL is available for Visual Studio 2010, 2012 and 2013, the Visual COBOL Personal Edition is currently available for Visual Studio 2010 and 2012 only.
The Visual COBOL PE for VS2012 product will not install into an existing VS2013 product. It will instead install a shell version of VS2012 and install into that.
The shell VS2012 and full VS2013 products can coexist on the same system..
Thanks.
