CB Error Help Request, c:

well, on behalf of a friend. I'd like to ask the community if they know a fix for an error. My friend has already reinstalled CB, many times. She also experimented with downloading using different browsers (IE, Firefox) but the error still appears, If any of you know how to fix it please post here, C: Or leave helpful suggestions, etc. Also, she's using Windows Vista

If it would be XP, it would probably run without problems.
If you use an antivirus turn it off download the game again and reinstall it.

Run cosmicbreak.exe as administrator or install the game client NOT in program files (aka any uac-protected directory).

I see, I'll tell her to try both of your suggestions & see if it will work, o: & thank you for your suggestions
