When I run the vsix, I get a simple dialog that says:
"This extension is already installed to all applicable products."
I did use this configuration section designer a while back, and I can't recall if I got a new PC before or after.
For the life of me I cannot find the config section project type template in Visual Studio 2010 or 2008 (which are both installed).
Maybe I need to uninstall this vsix and reinstall it? But how do I uninstall, I can't find anything on my PC for this, but I probably don't know what I'm looking for.
