I'm trying to upgrade my VUM from version 5 to 5.1 but i'm getting stuck at the point in the installer where you enter the credentials for the vCenter server, the installer hangs at this point and vpxd.exe and java.exe hit high CPU usage.
Digging through the logs it gets stuck running the vciinstallutils.exe vcversion check, running this manually give this output which rapidly repeats over and over again. Other plugins such as Remote Deploy and the ESXi Dump Collector register and install without issue.

Different users all give the same result, upgrade installation and fresh install also gives the same result.
I can't find any information relating to this issue and I can't see anything in the vCenter or SSO logs that would indicate a problem. I've never had a problem with VUM from version 4 onwards so i'm a little shocked as to the issues i've recently had with vCenter 5.1 as a whole.
Anyone able to help?
