I'm upgrading EPO 4.0 to patch 6 so I can then upgrade to EPO 4.5.
During the install I log on as a global administrator with a simple password.
The install looks good till the end where the EPO400-Patch-MSI.LOG reports
Failure: Failed to impersonate the NT user.
Hmmm, I would have thought this would be a common problem with simple answer.
