I successfully changed it from 'Recommended location' [per-user] (which I assume is default) to 'Use a custom location' [/ProgramData on specified drive].
The check-box selection dot is present in the custom menu option.
The problem is it wont switch back; with the problems described in the previous post. (hanging or not applying changes)
Thought possibly this may be related to why settings aren't sticking. (administrator rights, access permission, registry permission etc)
Ok, On my side it still works (reads right config in user path) but if needed to go back to defaults settings this is what works.
Though I don't like mentioning this as you need to uninstall PL then open reg and delete "processlasso" keys in HKEY_LOCAL_MACHINE\SOFTWARE\ProcessLasso and also these two if Processlasso key is present HKEY_USERS\.DEFAULT\Software , HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ProcessLasso.
Then reinstall PL, you will need to enter license code again to activate but it will be back to defaults.The reason the key is not deleted on uninstall is so when updating/installing you don't have to redo activation info.
Edit All you need to do is remove the data lines configfile and logfolder in HKEY_LOCAL_MACHINE\SOFTWARE\ProcessLasso of the registry, no need to uninstall and reinstall. This is for default radio button sticking to custom path.
Just be careful, and always backup registry before editing it.
I will note this and hopefully we can get a cleaner way.
It's best to wait for a proper fix.
PS: my above comments are only for radio button getting stuck on custom config path, not a fix for columns as that is different issue AFAIK.
