Portable separate LB install won't work alongside current versions

[FlightRisk]

I can't guarantee I didn't break anything, but this was working before the last few versions. I have a separate folder with a full LB and LB.Next install from several versions back. I used to be able to stop running my main LB, go to that folder I use for testing, and run that version. Now it does nothing. If I click LB or LB.Next's exe, nothing happens. Same with BigBox. If I watch taskmanager, I can sometimes catch the exe showing, but then it just goes away. No error. I was using this to import my setup one platform at a time from that version (no-intro roms) to my new main setup.

I have 2 installations of LB and they both work just fine along side each other.

Is there a logging function where I can see what it is doing? If not, I can try to see what's going on with Sysinternals Process Monitor or just unzip it all from scratch again.

Check your task manager to see if there is another LB process running.
