Yes but not necessarily virus software fault... why does mine always install ok?? its some conflict with existing drivers, or install files... clean install windows, install ALL windows updates, ALL USB driver updates, Graphics card updates, as if it were a new PC, then and only then install the latest virus updates. If that does not work, i will eat my hat and give in and admit defeat..
Yes, i agree, you shouldnt have to do this, but everyones PC/Mac set up is different and access (or any other company) has no way of knowing every single users set up do they?.. you could have a peripheral causing conflict with virus drivers.. i have seen people on these forums having problems because their anti virus software sees the word "virus" in a file and stops installing causing problems, try switching your anti virus software off (if you have it.. which i hope you do) while installing VC.
Good luck
