Convert via right click context menu!

Adding to the context menu the option to run a script on individual .yyp and .gmx files will trigger a conversion to the latest version. The batch file (.bat) will automatically add keys to the registry, allowing the option to appear in the context menu. You right-click on a .yyp or .gmx file, select gm_convert_to_newest_ver, and a folder named _old_ver is created in the directory, where the current old project is moved. In place of the old one, a converted project in the new version is created. I also fixed bugs related to cloning platform options that everyone has in their profile. You just need to enter your own paths in the batch file:
SET "PYTHON_PATH=C:\Python310\python.exe" - path to Python
SET "SCRIPT_PATH=D:\Projects_conversion gm\gm_convert_to_newest_ver.py" - path to the script. If you need any further assistance, feel free to ask!
