I have definitely the same problem.
I've been fighting with this for couple of months. Still no results.
"Software Status" has question mark all the time for all servers. I installed two new HP SIMs on different machines - observe the same manner of HP SIM 7.4 version and latest SMH and VCA and VRM.
Of course, from server side VCA works fine - I can upgrade firmware without problems using VCA and VRM.
