FLVPlayer not loading (comes up with RMC4 installation)

Basically I tried RMC4 after using 3 for a long time, love it. But now I went back to 3 (having uninstalled RMC4 etc.) and it works perfectly but FLVPlayer will not load. I can load it fine if I start it up in the Program Files shortcut, but when I try setting .flv files to open with it automatically, an installation box comes up for RMC4.

I've tried cleaning the registry and reinstalling RMC3 but no luck. :(

Is it possible that the FLV player has already been upgraded that is why you need the lastest version of RMC so it will work well with the player?
