I have a problem with building the sample SDK code CExAPI. The compiler reported an error during execution.

Please note that some features, although present in the PDF-XChange API and PDF-Tools SDKs, will operate only in evaluation mode unless the PDF-XChange PRO SDK license is purchased. Specifically: digital signature support (in all products) and the low-level API functions in the PDF-Tools SDK.


I tried building the sample code - CExAPI - and the compiler reported the following error:

"C:\Program Files\Tracker Software\PDF-XChange PRO 3 SDK\Examples\APIExamples\CExample\CExAPI.rc(10) : fatal error RC1015: cannot open include file 'atlres.h'.
Error executing rc.exe."


The Windows Template Language (WTL) is not installed on your system.
