Hi,
I can’t open MS Office files directly. When I try, Windows Installer starts then fails as MSOCache\All is not accessible, Error 1706. However, I can open these files from their respective program. I run Office 2016 Pro Plus, 64 bit, on Windows 8.1.
This started when I installed Windows security update for Adobe, KB4477029; I have Acrobat DC on my laptop, and this is integrated into Office.
I’ve tried to uninstall this update, it doesn’t listed though among the installed updates; while it is shown in update history. I tried to reinstall it manually; I was told it had already been installed. I’ve found some update repair in Windows’ website, ran it, nothing happened.
Thanks for any help.
