Why doesn’t StampPDF appear in Acrobat?

If StampPDF does not appear in Acrobat, then most likely Acrobat is set to “Certified Mode”. The “Certified Mode” option began with Acrobat 6.  Certified Mode is intended to restrict any third party plug-in from running under Acrobat. Certified Mode is usually checked when you install Acrobat.

Take the following steps to turn off Certified Mode.

  • Acrobat 6 – Go to the Edit Menu > Preferences > Startup – check if the “Use only certified plug-ins” is checked under “Application Startup.” If this box is checked, uncheck it, hit OK twice, close and reopen Acrobat.
  • Acrobat 7 – Go to the Edit Menu > Preferences > General. Choose StartUp in the left column – check to see if you have “Use only certified plug-ins” checked under “Application Startup”. If this box is checked, uncheck it, hit OK twice, close and reopen Acrobat.
  • Acrobat 8, 9, X & XI – Go to the Edit Menu > Preferences. Choose General in the left column – check to see if you have “Use only certified plug-ins” checked under “Application Startup”. If this box is checked, uncheck it, hit OK twice, close and reopen Acrobat.

If you continue to have problems with StampPDF Plug-in, then you should take one of the following steps:

Choose Help > Detect and Repair, or Repair Acrobat Installation, depending upon which version of Acrobat you are using. The StampPDF menu should appear when you reopen Acrobat.

If that step does not work, then you need to uninstall and reinstall Acrobat. Follow the steps to turn Certified Mode off and then reinstall the StampPDF.
