I'm trying to install an update to Digital Photo Pro (Canon). I have the CD, I have an older version installed (3.3xx), so this isn't a pirate thing. Everytime I try to run the install file, it starts to extract then I get an error "failed to extract the files". Much searching has only found me that people who use Kapersky anti virus have to disable it. I dont use Kapersky, but I disabled everything anyway, but I still get that error. Anyone have any ideas?
