I’m installing Office 2007 on a Windows 10 virtual machine in the hopes of opening some old Word 5.x files. Windows Update installed quite a few security updates, but the Microsoft Office File Validation Add-in failed with Download error 0x80240023.
The first hit when I googled that error code was someone else with the same issue. Of the 78 replies, this one was highlighted as the answer, and worked:
- Go to C:\Windows\SoftwareDistribution\Download
- Find OFV.CAB and extract it. You’ll have OFV.msi
- Install it and hit Retry on Windows Update.
Sure enough, after the manual installation, the file is no longer offered by Windows Update.
Word 2007 is still not recognizing a Word 5.x file even though it works on another computer (an old Windows XP machine). That’s a separate issue.
