PostSetupConfigurationTaskException - Failed to upgrade SharePoint Products

I just upgraded a SharePoint 2010 site from the RTM load to SP1 (KB2460045) + June 2011 CU (KB2536599). Running the Products Configuration Wizard (psconfig) ended with the following error:
Task upgrade has failed with a PostSetupConfigurationTaskException An exception of type Microsoft.SharePoint.PostSetupConfiguration.PostSetupConfigurationTaskException was thrown.  Additional exception information: Failed to upgrade SharePoint Products.

File that under useless error message.

Then I found this post: http://sharepoint.stackexchange.com/questions/16104/sharepoint-server-2010-sp1-psconfig-issue/21031#21031 which suggested to Run As Administrator on the Products Configuration Wizard. That worked.

Missing FAST Administration Links

I just upgraded some of my sites to SP1 + June CU and the Administration Links for FAST disappeared. Very simple fix described here: Updating SharePoint Server 2010 from RTM to December or later Cumulative Update disables FAST Search links in site collection administration (KB2521577)

Unable to install Hotfix for Microsoft Windows (KB976462)

While installing FAST Search for SharePoint, I came across this error:
Error: The tool was unable to install Hotfix for Microsoft Windows (KB976462). If Hotfix for Microsoft Windows (KB976462) is already installed you may need to uninstall it and run prerequisite installer again.

It turns out all I have to do is run the installer again since I was running Windows 2008 R2 SP1 which already has the necessary fixes.

Reference: KB2581903

KB2560890 update without SharePoint SP1

It appears that the Security Update for Microsoft SharePoint Server 2010 (KB2560890) breaks the User Profile Service Application if you don't have SP1 installed for SharePoint 2010. The error I am seeing is:
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.ResourceManagement, Version=4.0.2450.34, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified
According to UserProfile not working after security update KB2560890, it seems like others are having the same issue.

The file list for KB2560890 refers to version 4.0.2450.34 of various Microsoft.resourcemanagement.* files, but does not specifically list Microsoft.ResourceManagement.dll.

In my GAC, I see the following:
Microsoft.ResourceManagement 4.0.2450.5

Microsoft.ResourceManagement.Service 4.0.2450.11

The machine had rebooted from the Windows Update. So, on a whim I decided to try shutting down and restarting the User Profile Service and the User Profile Synchronization Service (remember to iisreset if Central Administration is on the same machine).

I then checked back in my GAC and now I see the following:

Microsoft.ResourceManagement 4.0.2450.5
Microsoft.ResourceManagement 4.0.2450.34

Microsoft.ResourceManagement 4.0.2450.11
Microsoft.ResourceManagement.Service 4.0.2450.34

Microsoft.ResourceManagement.Service 4.0.2450.11

I can also manage my User Profile Service Application!

There's some sort of voodoo here, but as far as I can tell it works. Perhaps there was a continuation task after the Windows Update reboot that required yet another reboot. Who knows?!

Argh! Spoke too soon. If I go to Setup My Sites, I now get the following:
Cannot create an object of type 'Microsoft.SharePoint.Portal.WebControls.LocStringId' from its string representation 'SiteAdminPersonalSite_SocialSecurityTrimmerEnabledSectionTitle_Text' for the 'TitleLocId' property.

Time to give up and just do SP1 sometime in the future.
