Data Execution Prevention


If on your first run Liberty BASIC fails with "a non-continuable protection violation has occurred. Check ERROR.LOG file." you
need to check your DEP settings.

The Windows default setting for DEP is "on for essential Windows programs and services only". If your system has a more
restrictive setting for DEP, your PC will be of limited use for programming, any programming, not simply Liberty BASIC
programming. DEP might be on in a corporate environment, where computer systems staff don't wish the PC altered in any way.
In a home or office environment it is not required.

It is recommended you turn DEP on for essential Windows programs and services only, adding Liberty BASIC to the exception
list is not sufficient.

To open the Windows help, which describes how to achieve this, use one of the following procedures:
  1. click on Start and then Help and Support
  2. hit [Windows]+[F1]
  3. hit [Ctrl]+[ESC]+[F1], if there is no [Windows] key available

When the help window opens enter DEP or data execution into the search box and click on the magnifying glass search button.
There will be an option that says "Change Data Execution Prevention settings".
Click on that and follow the instructions.
