Win 7 SP1

We're running zcm 10.2.2. Agents on Win 7 deploy successfully, but not Win 7 SP1. We get the code 21 error "could not determine device type from OS" message. Should I expect that the 10.2.2 agents are incompatible with SP1 computers and always will be? I tried upgrading to 10.3.x a couple of times and went through lots of pain before having to revert to 10.2.2.
