Issue
When launching a product from the Foxtrot Suite it is closed immediately, sometimes followed by an error message. This can be a result of the “Data Execution Prevention (DEP)” settings blocking Foxtrot programs from running. This typically happens after a new installation when attempting to activate licenses, but can also be a result of a Windows update that has reset the DEP settings.
Some versions of Microsoft Windows are equipped with this feature known as DEP. DEP is a set of hardware and software technologies that perform additional checks on memory to help prevent malicious code from running. DEP prevents such malicious code from taking advantage of the exception-handling mechanism in Windows.
DEP software works alone or with compatible microprocessors to mark some memory locations as “nonexecutable”. If a program tries to run code – malicious or not – from a protected location, DEP closes the program. To use DEP, your computer must be running Microsoft Windows XP SP2 or later, or Windows Server 2003 SP1 or later.
Foxtrot applications contain proprietary technology to interact with the presentation layer of target applications. In doing so, Foxtrot applications may be required to work with memory locations outside of its own running processes. Therefore, to allow Foxtrot to run properly, it must be added to the system’s DEP exception list. The following files should be included:
