Building trunk of today fails on Windows: Error: Invalid DLL
C:\WINDOWS\system32\common.dll, invalid header size

Here's how I managed to fix it.
Finally good news.

In taskmanager I had to stop one process,then go to services, find
xtu3service.exe, right-click, then "open services", find that service
again (now called XTUOCDriverService) in the newly opened window,
right-click, select properties, then set Startup type (? "Opstart
type") to Disabled.

After a reboot I was able to rename that common.dll to _common.dll,
rebooted again.
All this as administrator of course.

Finally after all that I was able to build fpc for 32-bit.

And if that does not work maybe this can help?

Looking with Windows Explorer at the Common.dll in question:
Productname: Intel(R) Extreme Tuning Utility
The guide on how to remove this utility:
That unfortunately did not work for me, hence the solution above.

At least it may give you some clues where to start.
