hi there.. i have updated the code to get better info about the error
Code:
#include <stdio.h>
#include <windows.h>
int main()
{
	LONG result;
	result = RegDeleteKeyValue(HKEY_LOCAL_MACHINE,L"/SOFTWARE/MYKEY",L"VALUE");
	LPVOID lpMsgBuf;
	FormatMessage( 
		FORMAT_MESSAGE_ALLOCATE_BUFFER | 
		FORMAT_MESSAGE_FROM_SYSTEM | 
		FORMAT_MESSAGE_IGNORE_INSERTS,
		NULL,
		result,
		0, 
		(LPTSTR) &lpMsgBuf,
		0,
		NULL 
		);
	MessageBox( NULL, (LPCTSTR)lpMsgBuf, L"Error", MB_OK | MB_ICONINFORMATION );
	LocalFree( lpMsgBuf );

	return 0;
}


and i am getting "Das System konnte die angegebene Datei nicht finden"

any ideas??
