Hi Terry,

>Does ISE offer a create registry key because permissions are more liberal during an install than during runtime.

Absolutely. On my machine your application would probably fail, because no code can write to the HKLM branch of the registry. You can read most information, but then you need to mask a security mask that only request read permissions.

If the application needs to write to the registry, you can either use the current user branch instead of local machine, or only administrators and power users can use the application. In this case, you should add a check if the user has sufficient prrivileges.
