Why won't the installer work?
 

I dowloaded the installer and everytime I try to install it, a warning message pops up
saying the app. crashed due to an Unknown trap type exception (debugger/debugstr)
I tried both Limewire and Furi and I get the same message for both. Anyone have any
suggestions....please help!

Unknown trap sounds like something is missing in your OS, especially since you got two applications to error. You could reinstall MRJ, update CarbonLib, or run an OS updater again. All of these actions put back or update various expected elements in your computer.
