Our digital code signing certificate has expired. Until we get a new one you will have a screen as follows if you try to install CDS or Ezigrade.
Simply click on "More Info" and you will see the option to "Run Anyway".
If someone wants to ask Microsoft why it is impossible to install an application with an expired certicate, you get large red screen. I would love to know the answer. Rebuild it without any certificate at all then you get screen above, which most people are used to anyway!
