Let me start by saying that if I start with a fresh 1607 install, then install ZEN agent 11.4.2 and then upgrade to 1709 there are no problems.

Now I have created a new win10 1709 MDT install and during the agent install I get a message about ZESM File System Filter Driver failed to install and then when the system restarts windows reports there was a problem and I get stuck in an Automatic Repair loop. The system will work fine right until I put the zen agent on then its toast. Any ideas?
