Today, I downloaded an Excel sheet which a friend had mailed to me – and was taken aback when my Microsoft Office was unable to open it! I then checked and found that I was unable to open Word or for that matter any Office program files!
I received the following message:
This update package could not be opened. Verify that the update package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer update package.
I was surprised, and although I do not know when exactly this had happened, it could probably have been after the Windows 8.1 upgrade, which I had carried out only two days back. I checked if the MS Office cache files (MSOCache hidden folder) were still present on my System Drive. They were there!
I tried to run the Office Pro setup from there but recieved this error:
This patch package could not be opened
