x64 version issues
4 posts • Page 1 of 1
My app calls a DLL to do some number crunching (geographic coordinate conversion). This works fine in the un-protected and enigma protected 32bit version of my app and also in the unprotected 64bit version. But once I protect the 64bit version the calls to the DLL no longer work. The DLL is being loaded, a handle is being returned by LoadLibrary, but the next step: GetProcAddress returns nil instead of a structure as it does in the 32bit and unprotected 64bit versions.
