Can't Update ArmA 2 client to beta

[Olmec]

I've tried a few solutions so far to no avail. I am currently running on 1.60.8xxxxx When I attempt to install the beta patch acquired from arma2.com/beta-patch.php "1.60.93965" after the installer finishes extracting I receive a dialogue box labelled.

"Bohemia Interactive Patch"

"You have no access rights to install the application."

I'm at a total loss. I've tried re-downloading thinking it's corrupted and using a different extractor, turned off user-account control, disabled Kaspersky, run as administrator, editing the registry as described in forums.bistudio.com/showthread.php?90317-!Beta-Troubleshooting-Tips-FAQs but I'm out of luck.

Possibly relevant build information:
Windows 7 Home premium: 64 Bit
SSD drive running in RAID 0 (Autocad w/ drafting projects), and HDD on it's own where I keep Steam and ArmA.

You can download it over Six Updater also; http://www.six-updater.net/p/about.html

The following link should work once you have installed the software, and at least have ran Six Updater (not launcher) once:
