Thanks Joel.
I am getting error message 1638 from the event log, meaning that another product version is already installed. I usually get that error prompted in the deployment console but it just gets hung there. Its been 2 days and it still stuck at executing script.
Besides this job, there are many other jobs having this issue that we normally dont. For example, we have a standard package group that gets rolled out to every pc after imaging. After SP6 upgrade, few of those job actually fails and report an error 1. I had to add an exception to error 1 and then it proceeded onto the next time. We never had these errors before with the thousands of pc we imaged in the last year.
Any help would be greatly appreciated.
Thanks
