I have a licensed copy of Visual GDB which is installed in Visual Studio 2017 Community.
I upgraded to Visual Studio 2017 Professional (I have both versions on my machine) however, Visual GDB will continue to update in Community but will not install on the Professional version.
Can someone give me a clue as to how to get this installed in Pro ?
Yes, please edit the HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\VS7\15.0 value in registry to point to the VS Professional folder and then uninstall VisualGDB and install it back. This should get VisualGDB to recognize the correct VS instance.
