ActiveX Control for Flash Player could not be registered

I have the latest Flash Player installed but a program that uses IE (Everquest 2) doesn't seem to recognize it and I get this error when the program tries to install the latest Flash Player anyway

I've gone through ALL of Adobe's Flash Player  support. Uninstalled Flash Player. Reboot twice. Install newest Flash  player. Reboot twice. Same error. I've tried running the launcher and Flash Player  installs "As Administrator" in every concievable way possible. I've  disabled firewalls and antiviruses. I'm not a novice computer user &  have tried just about everything. Coming here for help was my very last  resort.
