Simple just check in the video option i the right upper corner the number, for BI it should be 1.6 and for Rome 1.5.
If you installed Rome + 1.3 + 1.5 + BI + 1.6 + Alexander (is 1.9 if not mistaking )
then wen you check it should be ok ..
Another way to check right click on the exe file and see the Version it should be for Rome 1.5 and BI 1.6
Hope this helps .. good luck
