PRB: Unable to install 4 line add-on with older Zetafax systems

Print

ZTN1373

ID: ZTN1373

This Zetafax technical note applies to:

  • Zetafax version 8 or earlier

Symptom

When attempting to install a 4 line add-on on a Zetafax 8 or earlier system, the Zetafax Configuration program rejects the licence number with the following error message:

'The upgrade or add-on number you have specified is invalid, or has been typed in incorrectly'.

Cause

The 4 line add-on was introduced with Zetafax 9, and is not recognised directly by older systems.

Resolution

The licence number for a 4 line add-on has the format " Uxxxxxxx-LINE4-xxxxxx" .  To enter this with Zetafax 8 or earlier, replace the text LINE4 with the letters AAAEAA.

ie

                      Uxxxxxxx-LINE4-xxxxxx

should be entered as

Uxxxxxxx-AAAEAA-xxxxxx

Status

This is designed behaviour, caused by an enhancement in a later product release
