Hi AlexvGeorge,
Nishant is correct.
Your application must run as an admin than only you create registry.
you can allow your application to run under user account control (UAC) with elevated privileges.
If your application is COM component than use Com Elevation Moniker else Update property ReuireAdministrator.

Thanks Shilpi,
I need to register a decoder fitler (.ax) with windows mediaplayer to play a file with custom extension. Do you know how to do this using the registry.

There is one tool Sysinternal. Search this on net and execute it than filter it with operation "SetRegistryValue" and than set manually the file with Window Media player. Now you will get all the registry value to set for particular file. Now do set all there registry value programatically.

If UAC is enabled, you will need to elevate permissions first, and then call RegCreateKeyEx (do not call RegCreateKey - it's obsolete now). Irrespective of UAC, you still need to be running as an Administrator (although with UAC that will still require elevation to run with actual Admin privileges).
