Hi,
I have MMM Premium 2021, which is installed on a primary computer and I want to install it on a second computer. My original purchase of MMM has no serial number or key code associated with it, so I can't install it to my second computer from my account. I installed the free trial version of MMM Premium 2025 on the second computer so I can log into my account, but I can't complete the free version installation without registering or entering a serial number. Any ideas?
