IMHO, your file associations are f**ked up. Some programs like to change them. But, since Lithunwrap is basically a "install it yourself" program, it means somebody else did it. Either you are running the program from the desktop, or you are clicking on the .exe file directly from the Windows Explorer. Try both ways to run the program. If that doesn't fix the problem, then your file associations with .exe files are probably screwed up on your computer. Look at my computer. I click on a .jpg file, and MS Internet Explorer starts up. Does that mean something strange is going on? No, that's where the file association for my .jpg files points to.
