Hello everyone. This happens when I tried to installed Far Cry. I installed it the first and then I uninstalled it. Then I install it again. So please let me know. Here are my computer specs:

My laptops reg:

Window: Vista Premium
Processor: Intel(r)Core(tm)2 Duo CPU T7250 @ 2.00 Ghz
Memory: 2046 MB
System type: 32-bits operating system
Video card: Nvidia Geforce 8400M Gs

I don't have Vista, but a search on google for "vista error 1603" or "error 1603 vista" should bring up some interesting reading.

Also make sure your installing with an account that has ADMIN permissions.

Good Luck
