    Extension does not contain valid signature

    Pierre-RAFFA Community Member

      Hi all,


      I open again a thread about a problem at our extension installation on several computers.

      Few persons can't install our extensions. They get this message: " The extension xxx does not contain valid signature. The extension will not be installed"


      Our plugins worked always since the beginning ( about December 2010 )

      Our certificate is valid and has been created by TrustCenter.

      I use ucf.jar with correct parameters...


      I thought that's a manifest problem. So, I tried to generate plugins from Extension Builder trial version which generates manifest "automatically" but the result is the same. I also tried to get a release from a non-signed certificate ( 1024-RSA and 2048-RSA )....but unsuccessfull...


      How to get a extension with valid signature for all computers ?
