    Extension does not contain valid signature

    Pierre-RAFFA

      Hi all,

       

      During installation of an extension, a blocking message appears:

      "The extension xxx does not contain valid signature. The extension will not be installed"

       

      Does someone know what it means ?

       

      Thanks.

          The extension you are trying to install is digitally signed. The failure of installation can occur due to the following reasons.

           

          1. Either the package has changed since its packaging.

           

          2. Either the signature is invalid.

           

          If you have acquired the extension from a third party, please verify that the contents of the package you are using are correct or that the package has not been altered with.

            The problem seems to be different because the extension works correctly on all computers except two where there is this message.

            So, we are trying to find differences between computers where extension works correctly and the two others but no differences ( same OS, same indesign build, same ExtensionManager build ... )
