If you're a user of the Avast antivirus, be advised to add CodeMeter and Steel Beasts software to the exceptions list. Searching for "Avast" in this forum will yield numerous threads with numerous problems in the past, over such a long period that I'm skeptical if they will ever be resolved by the company.
Other antivirus products might cause a problem too, but if so they seem to be more rare and of a transient nature.
