check the registry

Looking for a utility/program that Uses the GetSetting and SaveSetting commands.

Basically, I need to add an exe or dll file to my existing exe so that it can perform a check on the user's registry and identify if a specific registry key entry already exists. If it does, then it can continue with installation, if not, it will redirect user to a url to download the required software.

Thanks

It's easier to use a DLL than an EXE. Simply place your functions in a DLL and call them from your App when necessary.
