Agent version mismatch

Agent version mismatch

Hi,
we decided to avaluate Desktop Central and now have few problems:
Server
Central Server
:
10.1.2137.4
Distribution Server
:
10.1.2137.1
Agent verison mismatch: if You try to push agent from DTC server, agent installing from old msi and mst file has many fake addresses, that are used in installed agent config. Also server says, that agent needs to be upgraded. The same if You download agent from agent page to deploy through GPO. If You download LocalOffice_Agent.exe - version is up-to-date and everything works like a charm.
Agent version in push: 10.0.50.W
LocalOffice_Agent.exe: 10.1.2137.2.W
Why then deploying agent used self-signed certificate if I have configured https with our infrastructure PKI? Is it possible to use our own certificate?
Can I generate mst myself or edit current one? I don't want dummy server entries and fake DS servers in client config.

Sincerely,
Viktoras
