BioShock Activation Issues, Help!

[Redsonic]

I installed bioshock on my PC, then let my brother install it on his user account so we could both have fun.

However, my brother is having issues installing it on his User Account

What's Going On?

Please give more details about the problem. I cannot help you with such a value description of the problem.

Is there any error messages, if so what are they?
