Windows Vista was not officially supported by Lucatec® Mask prior to version 2.2.0. This particular issue has been resolved in that version. It was caused by an incompatibility with Vista-specific changes to the so called "DEP Hardware Protection". Disabling that feature of the operating system has reportedly worked as a workaround for a number of customers. Here's how to do that if you do not want to upgrade Lucatec® Mask yet (steps courtesy of tech-recipes.com):

  1. Click Start
  2. Click All Programs
  3. Click Accessories
  4. Right Click on Command Prompt
  5. Left click on Run as Administrator
  6. Click the Allow button if it asks you for permission
  7. Type or copy and paste this into the command prompt window:
    bcdedit.exe /set {current} nx AlwaysOff
  8. Hit enter and you should see the confirmation: Operation Completed Successfully
  9. Reboot and DEP should be off.
