Vista issues

Older versions of the plugins are known to give problems on machines running Windows Vista. Typically, the host application will freeze or crash as soon as you attempt to use the plugin; plugins from many other suppliers will exhibit the same behaviour. The problem can be avoided, however:

[1] Ensure that you have the very latest versions of the plugins - if in doubt, go to the downloads page and get the latest versions from there!

[2] Try disabling DEP (Data Execution Prevention) for your host graphics application. DEP was introduced in Windows XP but was disabled by default and so didn't usually cause problems. In Vista it's enabled by default, and so usually does cause problems. You can disable DEP by the following procedure:

  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.
