Sorry about that - it's the .dll registration service error message that is noted in the "Troubleshooting - Please Read" sticky. I've followed the directions about logging in as administrator, and also right-clicking on the shortcut icon and trying to run as administrator, but the same message keeps coming up:
"You do not have permission to run the required DLL registration service for this application. Please log in as an Administrator, or right click the Application icon and select 'Run As Administrator' in order to proceed.
I'm sure it's operator error on my part, but don't know exactly what I'm doing wrong. Any ideas?
