I have been working with Microsoft Office 365 32-bit installation on my laptop with Windows 10 Pro 64-bit for a long time, and now need to replace it with the 64-bit edition. However, I can't do this. I removed the 32-bit Office using its native installer or even with the Microsoft Support and Recovery Assistant according to the article Uninstall Office from a PC, but this didn't help. When I launch the downloaded online 64-bit Office installer (OfficeSetup.exe), it always throws this screen:
Obviously, there are remnants of the 32-bit Office installation in the registry or on the hard drive that prevents me from installing the 64-bit version. Does anybody know how to find and remove them manually? Or is there another automated way to get rid of the previous 32-bit Office installation to install the 64-bit version instead?

I've managed to solve this problem myself. The following article in Russian helped me with that:
Actually it refers the scripts from the following GitHub repository:
I launched the vbs scripts from the command prompt with admin rights. Here is an example how to remove the remnants of Office 365 Click-to-Run on a pc with 64-bit Windows:
%SystemRoot%\SysWow64\cscript.exe OffScrubC2R.vbs ALL /NoCancel /Force /OSEThis combination of switches for the script allows you to see what the script does because every step is logged on the screen.
1Did you try to uninstall Office manually?
Please refer to the steps of "Manually remove a Click-to-Run installation of Office" in the articel "Manually uninstall Office".
If it does not work, I suggest you install 32-bit Office first, then uninstall it again for a test.
1On a computer with multiple users, is it possible for one user to have one user with 32-bit office and another with 64-bit?
To uninstall 32-bit and install 64-bit for me, do I have to uninstall office for every user and then install 64-bit for every user?
