APP-V Application Virtulization Management Server Service Failing to start

I had a problem on a new build APP-V environment where the
"Application Virtulization Management Server" Service failed to start

I checked in the APP-V Log file located here
"C:\Program Files\Microsoft System Center App Virt Management Server\App Virt Management Server\logs\sft-server.log "

The error message in here was
"Invalid root path : Z:\Sequenced Apps

This root path was i think the path i first used when installing APP-V I had since changed this to use a UNC path as opposed to a mapped drive via the APP-V Management console.

It appears the APP-V management console changed the path in the registry in this location
\\HKLM\Software\Microsoft\Softgrid\4.5\Server
SoftGrid_Content_DIR

But did not change the path in the APP-V SQL Database in the
DBO.Servers Table

Amending the DBO.Servers Table in the APP-V Database to the UNC path allowed the APP-V service to start correctly.
