On a development computer, where Webdev 2024 and the AS400 native access are installed, you should find the EASYCOM DLLs (eac2900as *. *) here (by default):
C:\WebDev2024\Programs\Framework\Win32x86 for 32-bit DLLs.
C:\WebDev2024\Programs\Framework\Win64x86 for 64-bit DLLs.
Copy the DLLs, depending on your case, 32 and/or 64 bits, on your Web server: in C:\Webdev 2024, next to the other Windev/Webdev DLLs.
