Check if you have the below applications in Program and Features:
Microsoft Visual C++ 2008 Redistributable - x86 9.0.30729.4148
Microsoft Visual C++ 2008 Redistributable - x86 9.0.30729.6161
Microsoft Visual C++ 2010 x86 Redistributable - 10.040239
Microsoft Visual C++ 2012 Redistributable (x86) - 11.0.60610
If you have a 64bit system you'll need all of them + the x64 versions.
If you're missing any of these download them from Microsoft and install.
If this doesn't solve the problem I'd suggest to kick your brother ass.
Also you can reinstall the game.
Hope this helps.
