I've tried increasing the xmx specified in the UpdMgr.bat and backup.bat but this doesn't seem to have had any impact.

Is there any way to workaround this problem, can I not take a backup when running this update.

The VM is already backed up so worst case I can restore.

I need to get our service desk updated to the latest as part of the TLS changes for Zoho integration so would appreciate any help.
