Problem: MrSid files cannot be viewed in ArcPad 8.0


After upgrading to ArcPad 8.0, MrSid files (.sid) can no longer be viewed. These files work fine in previous versions.

Solution or Workaround

The extension needs to be turned on manually.

  1. In the Options drop-down menu, select Advanced Settings.
  2. Scroll to the right and click the Extensions tab.
  3. Check the MrSID box, and click the green OK button.
  4. Restart ArcPad for the settings to take effect.
