PC MOBO failed, new MOBO run iTunes from the 'old' drive?

PC MOBO failed, new MOBO is WIN11 only, can 'see' old SSD but can I run iTunes from the 'old' drive?

I was not running the newer 3-part iTunes. I tried to operate from my previous Win10 SSD but the new MOBO will not run WIN10 (there was a warning on the new MOBO).

I tried downloading latest iTunes and eventually discovered its 3-parts. Downloaded Music part and started with SHIFT but it will not allow me to select the 'K' drive which was the SSD from my failed computer.

I tried coping iTunes folder from the 'old' SSD and insert it in the iTunes I downloaded but suspect I picked the wrong location.

At this point I decided I was guessing and changing too many things and uninstalled the multiple iTunes products and stepped away from the problem!

In my 'old' iTunes I had iPhones backed up, iPads backed up and would sync my Nano for my radio in my vehicle. I would like to have that ability again.

Thank you for any help you may offer!
