Win7 register in registry is failed

Question

I'm trying to register the DLL in Win7 registry (in XP its working). The DllRegisterServer is implemented as follow:

1. Succeeded - Call the RegCreateKeyEx function to register new key : \\HKEY_CLASSES_ROOT\\NEWKEY

2. Failed - Call the RegCreateKeyEx function to register new key : \\HKEY_CLASSES_ROOT\\CLSID\\NEWKEY

Any idea why?

Thanks

The Windows API includes a function GetLastError() . Most functions, including the registry access function include the error reporting by the LastError paradigma.

When you have your own code to register the DLL, ie you debug your DllRegisterServer , did you call GetLastError after a failed function call? You will get an idea of the reason, when you evaluate the return value of GetLastError() .
