When i doubleclick a project in the file explorer i want always use VS2015.
I looked in the registry and the value of HKLM\Software\Microsft\Windows\CurrentVersion\App Paths\devenv.exe is correctly set to:
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe
(like described here: https://social.msdn.microsoft.com/Forums/vstudio/en-US/568e32af-d724-4ac6-8e8f-72181c4320b3/set-default-version-of-visual-studio)
I assume there is somekind of version marker in the visual studio project,
Any hint on how to force to use 2015 (without uninstalling the old verison)
