All concurrent managers will not start

We installed the minimum baseline patches for 11.5.10.2 along with the July CPU patches. After doing that, the standard manager (fndlibr) starts but all of the specialized managers do not (invlibr). We have relinked everything, run cmclean.sql, shortened the system path variable, etc. without success. This is on windows. I am looking for suggestions on what else to try.

After having no success getting the managers to start, we cloned Production to DEV.  The managers then started.  We applied the base line patches for Projects and Assets and the problem returned. 

We are running out of things to try to get all the managers started.  There are NO error messages anywhere.  There is NO log for the managers that won't start.
