I have purchased two copies of EMC 9. One copy and rev c on the UPC label and the other rev b. When installed I get the following:
XP installed with rev b indicates 905B46H ENU
VISTA installed with rev c indicates 910B68R ENU
I am assuming the rev c is the latest. I hate the word "assume". So, if rev c is the latest does it make any sense to remove rev b from my XP PC and install the rev c using the key and came with rev b?
