File Validation Add-In for Office 2007

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.

Office 2007 1

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:

  1. Go to C:\Windows\SoftwareDistribution\Download
  2. Find OFV.CAB and extract it. You’ll have OFV.msi
  3. Install it and hit Retry on Windows Update.

Office 2007 2

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.

    How do you find the file in there, and how do you go about extracting it?

    I went to the C:\Windows\SoftwareDistribution\Download folder in Windows Explorer, then typed “OFV.CAB” in the Explorer search box. Once found, highlight the file as shown in the screen shot. It shows the contents (just as it would for a .zip file). Drag the OFV.msi file to your desktop to extract it.

    @Elsabe has provided a link to the File Validation Add-In in the Microsoft Update Catalog. Interesting that that is still out there even though the corresponding KB article 2501584 is gone. The catalog lets you download From there, you can extract OFV.msi. That OFV.msi has an MD5 hash of 6f36f038ac3e7f45e89abb20a45676cc, which matches the MD5 hash of the OFV.msi that I extracted earlier as described in the main article above.

    WOW……very helpful your explanation.
    This error in the update-mechanism of Win10 was bothering me badly and I tried a lot of so called “solutions” in the INet, but I couldn’t get rid of it.
    THX to your explanation, my Win tell me finally again: “You’re up-to-date !! ”

    Again THX from Vienna…you made my day ;-)

    When I try to download it I got information that it is not safe and download is not possible ???

    @Andrew, I don’t know what you are downloading and from where. I got a download error (see above) with Windows Update, then I was able to extract the installer from the Download folder. If I am uncertain about a URL or file, sometimes I use to see if the file has a known virus.

    Oh I see. Yes, browsers have started throwing errors on the Microsoft Catalog because the link is not HTTPS. Here’s a report on that from several years ago, but I think the browsers are just recently getting more strict:

    If you trust Microsoft, you can try the download. Then right-click on the file, select Properties, and confirm that it has a Digital Signature from Microsoft.

    Hi Mark, Many Thanks for that, I will try and we will see :-)

    Thanks Andrew. Looks like that was digitally signed by Microsoft in 2011, so it’s authentic. Whether it is safe or contains bugs is another question :).

    The file should be safe to download. Your browser is blocking it because the download request is being done over http and not https. I allowed the download in my browser (Firefox) and compared it to the version I took out of Windows Update (C:\Windows\SoftwareDistribution\Download) as stated in this post. I also compared it to a version on another system. All 3 of my copies are all digitally signed by Microsoft Corporation ‎Friday, ‎January ‎14, ‎2011 11:49:40 AM.

    Thanks for this post. I was having a similar issue on a Windows 10 machine. It wouldn’t let me accept the license agreement and just said (error encountered). Got it installed (confirmed via Programs and Features: Microsoft Office File Validation Add-In, Microsoft Corporation, 10.7MB, version 14.0.5130.5003).

    However, in Windows Update it was still sitting there waiting for me to review/accept the license agreement, which I could not do and I could not clear out the “stuck” pending OFV update.

    To clear that out, I went to “Settings > Update & Security > Windows Update” and paused updates for 7 days. Then I Clicked “Advanced Options” and toggled off “Receive Updates for other Microsoft products when you update Windows”.

    Finally, I rebooted (not sure if reboot was necessary), went to Windows Update, clicked “Resume Updates” and toggled back on “Receive Updates for other Microsoft products when you update Windows”

    It then checked for updates, didn’t offer me the Office Validation Add-In and declared “You’re up to date” with green checkmark.

    Thanks a bunch for this post. I was worried I’d have to shell out $$$ for a new Office Suite/365 never ending subscription or live with a “stuck” update indefinitely.

    The file hashes, digital signature info, and VirusTotal info I provided in my previous comment are for the OFV.msi file which is inside the cab file.

    The .cab file itself has a digital signature of: Microsoft Corporation ‎Monday, ‎January ‎24, ‎2011 9:27:35 AM

    and it’s hashes are:

    MD5: 42699399752ABEAFD0CADE19363C2FD5

    SHA1: 475DE2ECCFDDBB06F945EFB53472963E8FF88D0B
