Windows Agent fail to upgrade

Hello,

I'm not sure I've my Windows agents have ever updated with a manual upgrade, but they won't upgrade to v 5.11.
I've tried it on 2 servers, both Windows 2012 R2. One in a AD Domain and one not in a Domain.
When I try to force an upgrade, I get these errors in the event log:

Application: bmtcpagent.exe
Framework Version: v4.0.30319

Any help appreciated.

Version: 5.0.11

The agent could have had a failed update; so in this case, you should manually update the agent files (copy from a working agent), then start the service.

FYI - in 5.1, with the new agent model, this will be much less likely.

Hi,

OK, thanks. Just to let you know, this was from version 5.10 to 5.11.
