[GNC] Can I have two GnuCash releases installed in Windows 11

[Michael or Penny Novack]

You also  didn't specify whether you meant two versions both usable OR 
simply leaving an old version available for a quick build back out.

The reason I hate answering questions like this is if you don't already 
know how you shouldn't try it. So I'll only give hints. The installer of 
the new version will only uninstall the old version if it finds a 
gnucash directory in the program directory. In other words, the 
installer will work if you never had gnucash installed before, just 
creates that directory. It finds the old directory because it knows its 
name. Ask yourself what it would do if it didn't find a directory WITH 
THAT NAME in the program directory and how you could make that happen.

When I am making major changes to software I am usually set to quickly 
back out the change with just a couple renames << and remember to clean 
up afterwards >> This of course not simply a Windows thing.
