Premier Elements 11 serial key problem after 14 install

[victord20040655]

I bought and replaced PSe and PRe 11 on my PC some years ago with PSe/PRe 14 and recently bought a laptop which I thought I could put the old PSe11 and PPe11 on.  I have the retail disks(the combined PSe/PRe package) etc and was sucessful with PSe but PRe is coming up with invalid key, which indicates that I didn't decativate PRe 11 when I updated my PC.  No idea how I can get to PE11 as I have no computer with it on (no trace of it on my PC). Alternative is that I buy PSe/PRe 2020 for my new laptop but as 2021 is PC update year, I'm trying to keep software costs down for a bit. I checked my adobe account and neither of my packages are registered (can't remember if you could when I bought them).  Can I still deactivate my old key for transfer?
