If you receive Error Code 2007 or a greenish tint within Topaz Clarity and/or Detail, this is an indicator that you have Avast Antivirus software installed. Avast is currently incompatible with both Topaz Clarity and Topaz Detail.
By uninstalling Avast and replacing it with a different software, it should dispose of the problem.
This is a problem our development team is currently aware of, and will try to address with future upgrades of the products.
