My swtor not Install

I got the installer package to work using compatibility bypass (file properties>compatibility>Windows7>admin>apply>close). Doesn't carry over when it's done (only needed to load up your first time or if you have to reinstall for some unexpected reason). As for the launcher itself, try what Ahmxgrim suggested (but not with the same trick as the first-time procedure, that could be more trouble than it's worth as is usually the case for these kinds of games because security). And speaking of security, try setting exclusions for SWTOR game files, just in case you get the false-flag treatment. (In particular, Webroot and Bitdefender may initiate panic mode at a faster clip than anything else on your system.)
