Upgraded from PSE 15 to 2020. Apps won't start

[PaulFBarrett]

I had a working installation of PSE 15.  I bought the upgrade version of PSE 2020 and installed.  Installation went fine, with no errors although it took about 20 minutes/

The launcher screen loads but I can't launch anything.  A spinner appears and disappears again and nothing happens.

I tried launching the editor exe directly from Windows Explorer - the same result.

What next please?

This isn't the typical user experience Paul, so why you and not everybody else right?  I hear you [sigh].  See if any of these troubleshooting tips get you out of Dodge.  Hope it helps.

Thanks Phinny - looks like I'm in for a long night. 🙂

While I was waiting for a reply,  I uninstalled and reinstalled everything, and updated the graphics drivers - to no avail. 😞
