CS5/CS6 Crash on startup, possibly Wacom Related

Question

Hello everyone. I've owned a Wacom Bamboo and both versions of Photoshop for some time, and use them frequently. However, since my purchase of a Wacom Intuos5 Drawing pad yesterday and installation of it's drivers, Photoshop has failed to open- both versions crash during either the "Intializing" or "Initializing menus" stage upon startup. I've tried reinstalling CS6, uninstalling Wacom drivers, installing new versions and reverting back to the old, updated my Intel HD Graphics Drivers, yet I've still had no success.
After spending most of yesterday searching for a way to resolve this issue, It'd be great if someone here might have a solution to this problem.
Here's the crash report:

Answer 1

I am interested in your issues as I am about to install an Intuos 5 on my PC win7x64 for use with Ps and Painter.
Have you tried doing a system restore to before the Intuos install to get it back to working?
Did you see any errors in the Intuos install?
Was an AV program running; perhaps crashing the Intuos install?
Did you uninstall the Bamboo setup before installing the Intuos? maybe a common file causing crashes?
Using the latest Wacom driver s/w for Intuos 5?
