I've raised an idea for asking CA to also support patched versions of MS Project with the MSP-driver. Right now they are only supporting the particular version of MSP that was tested with a given CA PPM version.
Kindly review the idea and why not vote up!
Related to this, how are other CA PPM & MSP customers dealing with Microsoft monthly security patches.
Are you e.g. exhaustively or cursory testing the patches and securing everything works ok with the MSP-integration until you deploy the patches?
If you are using MSP2013 with the new driver, how have you dealt with the problematic MS patches (KB3114366, replaced with January patch KB3114510)? See this KB-article for the problem description itself.
