    ZXP - No valid signature

    lcl276 Level 1

      Hi everyone,


      I have been using a ZXP InDesign extension for many years across versions CS5 and CS6.


      I have just installed CC 2015 and I cannot install my InDesign ZXP extension. It tells me that the ZXP file doesn't contain a valid signature and the extension will not be installed.

      Is there a way around this? The website/user of the person I downloaded it from doesn't exist anymore so assume that any sort of update will not happen.
