Location of DLLs and interops
Q: Where are the interop files and DLLs installed?
The STU SDK includes two DLL files, one for 32-bit and the other for 64-bit systems.
They are installed in the following directories:
C:\Program Files (x86)\Wacom STU SDK\COM\bin\Win32
C:\Program Files (x86)\Wacom STU SDK\COM\bin\x64
The corresponding interop files are in the same location.
Please note that the STU SDK installer only registers the 32-bit DLL. If you want to compile a program for 64-bit you will need to register the 64-bit DLL using regsvr32.
This needs to be done from a command prompt with admin privileges.
