I have been trying to run ROTR using the installer, and it doesn't work. There is no splash screen, I just press launch, and nothing happens. What is interesting is that I have one unmodded copy of Zero Hour, and I copy the folder every time I want to install a new mod. I have installed 1.85, then 1.86. then the 1.87 beta patch, but nothing is happening. If I run generals.exe on another mod, it works, which means that my unmodded copy should work. Is there any way to play ROTR without the launcher? Thanks.

Simply rename all the .gib files to .big (for instance !!Rotr_Intrnl.big)
It should work
