FIX: 'Expired or revoked signature' error with Office addins document.



ID: ZTN1201

This Zetafax technical note applies to:

  • Zetafax 7.0 and later


When a user tries to open the 'Installing the Zetafax Office Addins' document the following error is reported, and the install buttons in the document will fail to function.


The signature which is required to enable macros under the High Security Level has expired.


Equisys has updated this document with a valid signature and it is provided as part of the Zetafax update ZFUPD_V751.EXE. This is available on the Equisys web site www.equisys.com/updates as a separate download for Zetafax users.


This behaviour was corrected in the Zetafax update documented above.
