I have been working since long on this & banning my head into it but unable to do so.
Requiring some help on how to uninstall all the previous python versions which are available in system with all the traces removed either from program files as well as from registry i wanted to remove every single entry of older versions.
I’m using below script to uninstall the previous versions it casing me some issue folders are not removing & even the entry from program files is also not removing. When trying to do it manually it’s not removing.
//Task kill
if {exists running applications whose (name of it as string as lowercase starts with “py”)}
waithidden taskkill /f /im py*
endif
//Remove previous version
delete __appendfile
delete pyremove.cmd
appendfile {concatenation “%0d%0a” of (“start /w msiexec /x " & it & " /qn REBOOT=ReallySuppress”) of ((unique values of names of keys whose (value “DisplayName” of it as string as lowercase contains “python” AND value “DisplayVersion” of it as string starts with “3.” AND value “DisplayVersion” of it as string < “3.12.4150.0”) of keys “HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall” of (x32 registries; x64 registries)))}
appendfile {concatenation “%0d%0a” of (“start /w msiexec /x " & it & " /qn REBOOT=ReallySuppress”) of ((unique values of names of keys whose (value “DisplayName” of it as string as lowercase contains “python launcher”) of keys “HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall” of (x32 registries; x64 registries)))}
