Scripts compress easy in NSIS.. but what takes the room up in an installer is the Models.. a Model will compress to about 2.8 MB with an average of 8 to 10 BMPs.. the more models, the more space required.. both Install Creator and NSIS are about the same in this area.. and Install Creator is better at compressing *.txt files...
Basically, you can do the scripts in NSIS, which will drive the size way down on the scripts, then package everything else in Install Creator Pro under maximum compression and maybe squeeze another 1 % out of the scripts and get everything else as small as it possibly can go under current available public compression.
All I am neding to know is What requirements besides v2552 patch, is needed for the server.. is the shiplist requiring OP + ? I want the installer to check for the component and if not installed, then prompt for DL of the missing component before install continues...
Anyhow.. hope that this helps.
