Problem with Gamergate.com Hector Episode 3 also
Mac Daddy Gonz,
I also just purchased Hector - Badge of Carnage from Gamersgate.com today 12/21/2011 (on-sale). I have same installation problem with Episode 3. Episodes One and Two install fine, but number three says it's not compatible with my version of windows 7 (64-bit). I believe Gamersgate has the wrong (or corrupt) version on their website for download and that Telltale needs to contact them with a functional copy. I've attached the errors and requested help from Gamersgate and Telltale. I'll update this post if I hear something.
P.S. I've re-downloaded the installer, the cached install files, run as administrator, and tried the Win XP compatiblity modes. Because Episodes One and Two work perfectly, I believe it's the 3rd episode installer itself that is the problem (either encrypted wrapper or the installer).
