Blackberry Desktop Software won’t install on PC “Installation files cannot be validated."

Blackberry Desktop Software won’t install on PC “Installation files cannot be validated."  KB article 28396 couldn’t get past # 4 because no digital signatures tab.  Removed desktop software initially because it would not update.

Ditto Mark, have been trying on and off for sometime. I think it has to do with operating system (XP in my case)
