Installed Photoshop Elements on Windows 10. Unable to enter serial number

[Talking Cat Photos]

I haven't used PE 2019 for a few years but today tried to install it on a Windows 10 Pro 22H2 box.  The installation went fine but when I tried to use it I was prompted for a 6 digit serial number whereas the serial number on my Elements packaging is 24 numbers separaed by hyphens!  I do have an Adobe account (as I have been running an Adobe Creative Cloud subscription on a Windows 11 PC for a few years) and I am pretty certain I created it when I first registered Elements in late 2018.  But my CC account does not mention that I own the Elements as well.  Can anyone suggest what I should do get Elements working?  Thanks

Sorry but this was user error!  I realised that the "6 digit serial number" was in fact 6 lots of four digit numbers which is exactly my serial number.  Wheh I entered that it worked.  Turned out to be a non-problem.  Ooops!
