It seems that Windows 10 KB4551762 breaks the installation process when installed on a shared location with Basic or Silent UI level.
Recently we’ve received some complaints from our users that they cannot install updates, be it a major upgrades or patches when the destination (install folder) is found on a shared location.
We have further investigated this behavior and we confirm this behavior. It seems that after Windows receives the KB4551762 update, once installed on a network location, the installed application cannot be uninstalled.
Since the upgrade means the uninstall of the old product version and the installation of the new product version, the upgrade process will fail as well.
Not just major upgrades are affected, it seems that you cannot install patches either.
During upgrade process, the following error occurs:
Code: Select all
Error 1315. Unable to write to the specified folder: Z:\AdvInst Testing\
Once you trigger the major upgrade, or patch installation from an elevated CMD, everything works as expected, it doesn’t matter if the upgrade is made with Basic UI or Full UI.
- Remove the problematic KB4551762 update
- Elevate the CMD and trigger the update/uninstall from elevated CMD
