add-in directory - 'Visual Studio 10' or 'Visual Studio 2010' ?

Question

On my local installation of VS2010 beta 2, I have both a directory called "Visual Studio 2010" and a directory called "Visual Studio 10" under %userprofile%\Documents. I placed my add-in under "Visual Studio 10\addins" and it loaded fine, so made that the target in for the .addin file in my add-in's installer.

However, I have had reports from users who says that their VS2010 add-in directory is located under "Visual Studio 2010\addins". Which one is correct and why the discrepancy?

(Disclosure: I used to have VS2010 beta 1 on the same system, so my machine may have been 'tainted' by the earlier release although I uninstalled it before installing beta 2)

Answer 1

I believe having Beta 1 installed is why you have two different folders.  The default is to use "Visual Studio 2010" but this can be overriden.

What you should probably do is check the registry for the right value. It appears to be under

HKCU\Software\Microsoft\Visual Studio\10.0\VisualStudioLocation

I'm not 100% certain about that so hopefully a moderator will correct me if I'm wrong :)

Answer 2

Thanks a lot, I'll change the installer to use that registry key instead.
