@manuboss Parse Line (deprecated) - doesn't mean it's unusable, it's still usable if you want.
Or you can use an alternative method called "Parse CSV string"
You asked this question, I think you are new, and the message cannot tell you all about your problem, because there is a lot of information as well as different use cases.
So you can follow the basic instructions.
Just noticed that the "LastVersion" file in the profile folder, as the name suggests, gets updated when the profile is opened with (another version of) BAS e.g. from 114.0.5735.91 to 117.0.5938.63. Therefore it's not suitable for our need to determine the original version of which a profile was created.
But at least can be said what was the latest BAS version that worked with it ;)
