I have the original AoE3. I try to install it and the installation gets hung up on "Removing Applications." Eventually it gives an error message , "Data error (cyclic redundancy check)" and will progress no further. I searched Google and saw a few reports of other games having the same problem; with a variety of solutions for those games.
Anyone had experience solving this for AoE3?
Have you tried the register wipe script? I have seen it on other posts on this forum.
