Same here, I had an Infineon folder on my desktop inside a folder with all my motherboard drivers. When I deleted it, I was able to install the update with no problem.
If anyone has a problem locating the Infineon Folder on their PC, the "Everything" app from voidtools.com really helps as it searches in seconds through every single file and folder on the computer.
That solution worked perfectly for me!
The odd thing is that the Windows Update thing appears to complain about the "Infineon TPM professional package" that allegedly would be installed on my Windows 10 computer and that would need to be uninstalled. In my case no such thing was installed; neither
the list of installed programs shows such installation nor a presumptuous program 'Total Uninstaller' was able to deal with it. It simplyu was not installed and also was nowehre to be found anywhere on the drive that Windows 10 is installed upon.
After using the "Everything" program (also available as portable zip) it appeared that the only Infeon directory was hiding somewhere in a dark corner of my Archive back-up drive that contained drivers for a very old (Win XP) computer. Deleting those (in
fact obsolete) folders did the trick and the Windows 10 fall update installed without any further complaints.
Thanks EP7, thanks "Everything".
