Thank you for this informations.
Ho yes I want the newest version
but actually it's that version that doesn't work on my new laptop, while the oldest works on my desktop.
I'd prefer fix the problem of course to install the latest version as I can.
Do you think that it's my licence that dosen't allows me the new version that I donwnloaded or doesn't recognize an upgrade or something, or some kind of conflict between the two version?
If I can't do the newest PT works, I'll be forced to get the version of year 2017 (I hope it will fix the problem).
