Problems Creating a Key under HKEY_LOCAL_MACHINE in Vista

We have written a C++ application that creates a registry key to store information in.  On XP computers it works fine and on most Vista computers (Home Premium) it works fine.  However on some Vista Computers it will not create the key.  Otherwise the program works fine, but the key is never created.
The key we're creating is in HKEY_LOCAL_MACHINE\SOFTWARE.  The command we're using to create it is
LONG lRes = RegCreateKeyEx(HKEY_LOCAL_MACHINE, "Software\\OurKey\0", 0, NULL, REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, NULL, &RegKey, NULL);

The user is logged in as an administrator. Does anybody have any Ideas why, in only a few cases, the key is not created?

I have the feeling that you're a victim of "Registry Virtualization" - see  http://msdn.microsoft.com/en-us/library/aa965884(VS.85).aspx ("Registry Virtualization")

Hi jkr,

One would think that Microsoft would embrace Registry Virtualization as a way to help slow the proliferation of worms and other viruses instead of declaring it obsolete the instant it's announced.

Security in Vista has changed, even though the user might belong to the Administrators group the process will not run with administrator privileges unless the user explicitly permitted it. You will have to create security descriptor through an instance of SECURITY_ATTRIBUTES structure and pass a pointer to the structure to the RegCreateKeyEx function (currently you are passing NULL for this optional parameter) and ask the OS to elevate the privileges.

You can try this open registry again,click edit then permissions make sure all users are set to full control.
Then create your new key then right click  you may get a pop up (windows security)click reorder,make sure all users are set to full.

Even if you log in as administrator, if you want your program to work correctly run it using "run as administrator". You can do this by right clicking on this program and select "run as administrator"
