This is close to what I want, but not exactly. I'm not looking for the Scan to Config window to pop up every time I launch the enabler. Instead, I want to be able to call it on demand, as needed. For instance, I want to have TelnetCE locked down so that users can't exit to the Avalanche Enabler window underneath but I also want them to have access to the Scan-To-Config utility. Ideally I want to use a key combination within TE that would launch a TE script that would in turn run Scan-ToConfig. This would allow me to launch the utility from within TE.
If there is no direct call I guess I guess I could perform the following workaround, taking advantage of the registry key that you've provided:
1. Set registry key scanner.config.autodisplay = Enabled
2. Call the Avalanche Enabler executable
3. Reset the registry key to scanner.config.autodisplay.disabled
