It seems that if the RegOpenKeyEx argument remains NULL, error law 2 is returned. EDIT 2: I’ve explored several solutions including using the TEXT() function on the subkey and changing the permissions to KEY_SET_VALUE, but I’m still getting a match error. I also tried RegCreateKeyEx.

The winreg.h header defines RegCreateKeyEx as a powerful alias that automatically selects the ANSI or Unicode version of this application based on the normally constant UNICODE preprocessor definition. Mixing the use of an encoding-independent alias alias with code that is not encoding-independent can lead to incompatibilities that result in compile-time execution or possibly errors.

I used RegCreateKeyEx application from Win32 (VisualStudio 2008) 64 for bitwindows (project made with x64 concentrate). He managed to create a register of records. Now I have a DLL file (created project along with x64 target) that also wants to manifest a registry entry, but the DLL may return error code 5 (yes! This is definitely a sign of denial of use).
