1st I would run a virus scan it. A lot of these files contain such things when d/l from p2p applications.

2nd LimeWire will only launch audio or video files.

3rd if you really want to launch this file you have to do it from outside of LW. You can use a program like windows explorer to locate the file, and run/launch it from there by double clicking the file.

I would be very suspicious of any exe files d/l from a p2p program, and take appropriate measures to protect your system, like running an anti-virus program on the file, and have it running while you launch the program.

I would also check it for adware and spyware before running the program.
