Could you run installer with
and from temp folder copy MSI install log, and any other error message that you will see during install. Keep watching and see where installer hanges and then at what point it rolls back?
Before running installer remove previous logs from temp folder.
Also post event parser and orion logs from server DB folder.
Let you know one thing "Roll back is same for all " but reasons are different so I wanaa see actual cause in your case.
McAfee Application Server service
McAfee Event Parser service
McAfee Apache service
Do you see all above them stopped, right and option to start them is grayed out?
Could you also give a try to restart SQL server service and SQL Browsing Service?
And also mention your current ePO version and the patch that you are trying to apply.on 5/23/13 10:32:38 AM CDT
My Recommendations in your CAse after analysing all logs and screen shots.
1.Enable SA user in SQL DB.
2.Access ePO https://server:8443/core/config
3.Change your user here to "sa" and confirm a successful connection. Apply the settings
4.Restart SQL Server service and SQL browsing Service
5.Run the wizard and when it comes to stop the services, open task manager and kill tomcate5.exe process(be quick to do that)
6.After it your installation must go smother.
7.If it doesnt Report back.
