Hi All,

I have created 2 variation of my application(app). Out of the two app, One app is pointing to server 1, and the other app is pointing to server 2.

Now when I try to update my app from an old version to a new version.
Out of the two app, The app deployed on server 1 works fine, whereas the app deployed on server 2 - gives me "The update is improperly signed." alert box.

  1. The app deployed onto the two servers are exactly same, except the appcast.xml url, as the appcast.xml fine is located on two different server.
  2. The sparkle framework used is same in both the app.
  3. The appcast.xml file is same, except the url in tag, as it is pointing to the respected server location where .zip file of application is stored.

Can anyone please help me to resolve this issue?

Thanks in advance.
