I'm unable to install the SAM 6.1.1 GA additional poller software while the primary poller is running SAM 6.1.1 HF1. The additional poller installer checks the version of the primary poller, detects the primary poller is running a newer version, and stops the installer (well, not quite...the installer splash screen just stays up in the background until you manually kill the process).
Here's the message for Server 2012:
Here's the same message for Server 2008 R2 (contains additional info not included on 2012):
I can't find a way to rollback HF1 on the primary poller. According to the readme, HF1 updates the SolarWinds.APM.Collector.dll. It also doesn't appear to backup the old dll, so I installed SAM 6.1.1 GA on a separate server, grabbed the GA version of this dll, replaced the HF1 dll on our primary poller, ran the config wizard, confirmed the GA version of the dll stuck, then tested the additional poller install again with the same results.
Has anyone else encountered/resolved this issue?
