According to kb51111 MID does not work with VSE 8.8 Patch 8.
McAfee Installation Designer
The version structure for McAfee Installation Designer (MID) is parallel to that of VSE. Only the corresponding versions can be used together (Example: VSE 8.8 requires MID 8.8).
A new version of MID is usually released within two weeks after the corresponding VSE release date.
The full install package VSE880LMLRP8 has been reposted and is now MID-compatible.
The reposted package build number is 188.8.131.529. Patch 8 itself is not affected.
I've attempted to use the posted update with the current MID, it still fails. Opened a ticket in December about this problem, told by the techs a new MID would be released soon and that the 1599 repost did not fix all problems due to the ways the Agents worked.
Any update as to when the new MID will be released? I keep checking weekly, but my management is now out of sorts about the continued delays. While an MID for ENS may be bouncing around, I do not have any plans for an ENS migration until next year.
