The file downloaded was "DEC VMS 5.5-2H4 (Jul 1993) [VAX] (ISO).7z"  I ran it through "TheUnarchiver" and it produced a folder with two files.  A txt file and "VMS 552h4 VAX.iso". I tried burning that ISO file but then I get the disk image is invalid error.

MicroVAX comes back to ">>>" prompt after a few minutes, no other messages. Should I expect to hear some noises of the plate at the bottom of the caddie moving sideways to expose the CD to the laser, etc?
