I'm upgrading SharePoint 2007 to 2010 using attach and upgrade method.
When running database upgrade a series of similar errors are shown in upgrade log (could not find some temp file with an unpronounceable name).
Feature upgrade incomplete for Feature 'PublishingSite' (Id: 'f6924d36-2fa8-4f0b-b16d-06b7250180fa') in Site 'http://intranet10'. Exception: Exception has been thrown by the target of an invocation. (Inner Exception: Could not find file 'C:\Users\farmadminuser\AppData\Local\Temp\z-jynvy2.dll'.)
Feature upgrade incomplete for Feature 'PublishingWeb' (Id: '94c94ca6-b32f-4da9-a9e3-1f3d343d7ecb') in Web 'http://intranet10'. Exception: Exception has been thrown by the target of an invocation. (Inner Exception: Could not find file 'C:\Users\farmadminuser\AppData\Local\Temp\3ldfh-oo.dll'.)
Can anybody shed some light on the issue?
