While trying to run MakeMKV tonight I got a popup saying

This DEMO version has is too old. Please download the latest version at http://www.makemkv.com

So I did.

I still got the popup. So I unistalled and reinstalled. Still getting the popup.

Read announcement forum: http://www.makemkv.com/forum2/viewtopic.php?f=5&t=1053

Already read that. Since the app exits after the pop-up, having the activation code doesn't exactly help.

Edited to add: found a workaround. Installed it on another machine, exported the registry setting, imported it on the machine with the BD drive

Are you sure that you are running 1.5.0? Please recheck in help-about

Again, once that message popped up, the application exited, so it was impossible to check the version. There was no getting past that pop-up.

I was finally able to load it by installing it on another PC, exporting the registry information and importing it.

However, once it was installed it wouldn't decrypt the blu-ray I needed to re-rip. I ended up finding a copy of version 1.412 which works fine.

That sounds terrible. Are you sure that you have used 1.5.0 downloaded from this site? May I ask what kind of BD disc it was and how the program failed to handle it, failed to decrypt, failed to recognize the movie or failed in other way?
