Firstly I just saw the new maps in the library and they are amazing. Good job. It looks alot better now.

Secondly Im pretty sure that the mod uses a script to give Ai factions free army stacks if they run low.

X-danger:
I remember a while ago I got the same error. I dont remember how to fix it but I know there is a way and I think it was rather simple.

Ok. After some searching I foudn this as the solution to your problem:
If the error message says something about deleting your temp folder and such, then it's an Installshield error. In that case do the following:

go to "C:\Program Files\Common Files\InstallShield\Professional\Runtime" and delete a folder named "0701". See if this solves the problem.
