During a "FREE" upgrade from Windows 8 to Windows 8.1 I get an error message after the "compatibility test".
It says I must "Remove Sentinal Runtime Drivers". But gives no hint as to HOW!
I've uninstalled several programs that use a "Sentinal" security key (USB fob) for their licensing.
Of course, as soon as I began to write this, windows erased the error message.
Anyone have any ideas?
