I wouldn't take that pop-up at face value. The color management module is an integral part of Photoshop and there's no reason whatsoever to post-install it.
It's probably the other way around: the plug-in messed something up. Third-party plugins cause a huge number of problems. Uninstall it and check for an updated version.
The Adobe CMM is an OS level thing, and not a Photoshop plugin.
Also, it's built into Photoshop and Photoshop does not see or need the external version.
The external CMM is just there for other apps that may want to match the results in Adobe products.
And the CMM is 32 bit only, and won't do a thing in 64 bit apps.
And no, to the best of my knowledge nobody else has reported any such conflicts with the Adobe CMM.
FYI - substituting a microsoft mouse for the wacom tablet allows use of Akvis Sketch, no problem. Looks like Wacom has a problem here, since Amazon's Kindle App for PC showed identical symptoms - won't take any mouse clicks from Wacom, but fine with MS mouse. Thanks for your help. Gary

Thanks for your response. Recent evidence points to Wacom's tablet driver, not the plug-in.
Fact #1 - another identical system with ms mouse worked fine so I swapped out the Wacom tablet and bingo, the Akvis plug-in works again.
Fact #2 - So does Amazon's Kindle for PC app, which also quit working after running the Adobe CMM setup I'd downloaded.
Suggestion - since there's a legacy for CS5 users getting the "you should download CMM" pop-up, yet no need to do this, maybe Adobe should remove the CMM download page from its website - or flag this download as unneccessary for photoshop users. All Best, Charles Pierce.
