Wrong Unit Format during compiling for Win64

I installed the latest version of TMS VCL UI Package (10.8.5.0). If I compile for target Win64, I got the error (Sorry error in German):

E:\Programmierung\Delphi Sourcen\Drive_Abwickler\Texte\AbwAddOns\abwtreenodes.pas(2201,18): error F2213: E2213 Falsches gepacktes Unit-Format: C:\Users\Public\Documents\Embarcadero\Studio\22.0\Dcp\TMSVCLUIPackPkgExDXE14.dcp.advmetrodlgs - Erwartete Version: 35.0, Windows Unicode(x64) Gefundene Version: 35.0, Windows Unicode(x86)
What is wrong here?

It looks like there is a library path mixup on your system, i.e. your Win64 path points to a folder with Win32 library files.
Is this Delphi or C++Builder?
What exact v11 version is this? v11.0, v11.1, v11.2?
