I'm not 100% sure either on how it works or should workI don't know and don't understand how the check works, but if 1.36 works in 1.38 and then in 1.38.3, then it seems like this is the current path. Maybe @doskabouter can correct me.
You can use 32-bit MP on 64-bit Windows.How can I update from version 1.36 to version 1.38.3? I'm only offered a fresh installation.
Shame on me. That's it. I forgot that this computer was still running the 32-bit version of MP. From now on, I will no longer do updates in the morningSo either perform an upgrade install of 32-bit MP 1.38.3.
