Microsoft has confirmed that there are scenarios in which Service Pack 1 for Office 2010 deployments can fail, with users being unable to resolve the issue themselves.The first upgrade for Office 2010 was released to manufacturing at the end of June 2011, when it also became available for download to customers around the world.
At the end of July 2011, the Redmond company started offering an update designed specifically to lower the rate of installation failures for Office 2010 updates.
Softpedia readers have already been able to read about the refresh, download and install it, but Microsoft only provided details about its purpose this week.
The software giant acknowledged Office 2010 SP1 failed installations and detailed the problems faced by customers.
For example, users attempting to upgrade Office 2010 through Microsoft Update can receive this error message: “Code 78F Windows Update encountered an unknown error.”
Grabbing SP1 from the Microsoft Download Center and installing it manually will also do no good for customers, since they’ll run across into an error message such as “The installation of this packaged failed.”
IT professionals who will look at the Officesuitewwsp1-x-none_msplog.log file, will come across this error message: “Error 1935. An error occurred during the installation of assembly component <component GUID> . HRESULT: 0x80131047.”
“Several root causes may cause error 1935 or error 78F during the installation of the Office 2010 Service Pack 1 (SP1). Typically, this issue occurs when Office 2010 was originally installed by using a temporary storage device,” the software giant explained.
As I said, KB 2553092 is already available for download, and is specifically designed to help customers deal with Office 2011 installation failures.
“This update fixes the error message that is reported during the product reinstallation from the Add or Remove Programs item in Control Panel. SP1 does not have to be installed for the error message to appear,” the Redmond company said.
“This issue may occur if the Windows Installer encounters a reference to a drive that no longer exists, or to a removable media device that contains no readable media. For example, this issue may occur when the Windows Installer encounters a reference to an empty DVD or CD drive.”
According to Microsoft there’s also a very simply workaround that users can employ, by placing either a readable DVD or CD in the optical drive or connecting a USB drive to the computer prior to installing Office 2010 SP1.
