Problem

Error when attempting to install an update through the CONNECTION Client.

Error message:

Installation Failed (0xFFFFFFFF)

Solution

This error could mean a system reboot is required in order to install. Restart the machine and try the installation again or Install any Windows updates then try the install.

Check the installation log from %temp% for errors. If you see the following error in the log:

This access control list is not in canonical form and therefore cannot be modified.

You have an invalid access control list on this folder “C:\Windows\Temp” and the CONNECTION Client installer can't modify it.

There's a PowerShell script that will fix the ACL format:
