Hi my upgrade to 7.5SP1 is failing with the following error;
Execution of Service Desk MSI Completed. Return Code: 1619, State: Failure
I am running the upgrade on our test environment from the web server , i have just run the "fix 7.5 installer" tool which appeared to run succesfully
I am reluctant to unistall the existing 7.5 installation completley incase this removes all of the IIS Config on the server (we run multiple instances)
any help gratefully received.
