You are attempting to install Update 2 for FIM 2010 for the FIM Service and it immediately goes to the last page with no error message. The installation screen states that the install finished
You capture a Windows Installer Verbose log file of the installation. In the log file, you find the following information as to why it failed. You will see DetectServiceAccount. This indicates
that the installation is failing while firing the DetectServiceAccount Custom Action.
Windows Installer Verbose Log File Information
MSI (c) (80:0C) [13:08:03:552]: Invoking remote custom action. DLL: %userprofile%\AppData\Local\Temp\2\MSI762F.tmp, Entrypoint:

Action ended 13:08:03: DetectServiceAccount. Return value 3.
The service is running with a UPN logon rather than DOMAIN\UserName.
I was not doing trying to do the Update 2 to FIM 2010, but I was trying to run the Synchronization Service Manager and got the error below.
"Unable to connect to the Synchronization Service.
Some possible reasons are:
1) The service is not started
2) Your account is not a member of the required security group."
But change the UPN information to DOMAIN\UserName format worked perfectly for me.
