Here's my experience:
I'm running the RTM edition of Visual Studio 2012 Premium on a computer where VS 2010 Premium is also installed.
I re-ran the SHFB Guided Installer, and it recognized VS2012 as VS2011 beta, but it appeared to succeed.
When I open a solution containing a SHFB project, I get a dialog saying the project type is not compatible.
This version of Visual Studio does not have the following project types installed or does not support them. You can still open these projects in the version of Visual Studio in which they were originally created.
- Documentation, "C:\Users\DMcGloin\P4\...\Documentation\Documentation.shfbproj"
When I try to create a new project, the SHFB templates do not appear to be installed.
Thanks again for all your efforts.
