VUM Re-install - Invalid SOAP port

I am attempting to re-install VUM after upgrading to vCenter 5 and getting the message:

Invalid SAOP port number or TCP/IP port is already in use.

I have tracked that port (8084) back to Java using:

netstat -ano | more

Which reveals that the process using port 8084 is 1456 and then:

tasklist /svc /fi "pid eq 1456"

Tells me that 1456 belongs to Java.exe

I do not actually want to change the default SOAP port (8084), how do I get VUM to re-install?

P.S. VUM was upgraded and worked, but then failed. After a lengthy diagnosis, I opted to un-install and then re-install. That's how I arrived at this predicament.

THX in advance-
