I need to rollback MS Office365 to a version earlier than Dec 16,2021 because that version has introduced a filelock error in MS Access that makes my custom applications crash. This is a known issue.
I have tried using the officedeployment setup.exe /configure option with the suggested xml script:
<Configuration>
<Add OfficeClientEdition="32" Version="16.0.14701.20226" >
<Product ID="O365BusinessRetail" >
<Language ID="en-us" />
</Product>
</Add>
</Configuration>

However this crashes. I have tried over 20 times with two different computers / two different networks/ local and network admin credentials. completely uninstalled all previous versions of office etc.
Here is a screenshot of the error I recieve:and please note I AM connected to a high speed internet connection with all AV software and firewalls turned off.

    Hi @Jawsurgeon

    Thanks for your sharing.

    Please make sure your ODT tool is the latest version.
    Besides, to rollback Office to one specific version, you could also try to run following command.

    Such as "C:\Program Files\Common Files\microsoft shared\ClickToRun\officec2rclient.exe" /update user updatetoversion=16.0.14701.20226

    Any updates, you could post back.

    Thanks Emily:
    I have now tested the rollback using Access Desktop and my application now works as expected. Just and FYI : this filelock issue was introduced during the Dec 2021 update and broke my frontend/backend multiuser application. The code to add new records to multiply related recordsets failed.
    Using this rolloback (September 2021) the issue is now fixed.

    thanks.
    I have (at least for now) solved the roll back by changing the ID of the build in the script to an earlier version
    I don't know why I didnt think of that before but now (at least on 1 machine ) works.

    Version="16.0.14527.20234"

    I have not confirmed yet whether or not this solves the file lock problem but will update this post as soon as I do
