-        Changed the Exec start subprocess/ run py file to use the sys.executable 
-    4.54.0.2
-        Change from pythonw to python if the main or upgrade sys.executable found to be pythonw. This seems to be the difference when psgupgrade fails.
-    4.54.0.3
-        Also change from pythonw to python in the github upgrade call to pip
