I initially tried installing KIS 2013 from a CD that I had purchased last year and I received a message saying that the Digital signature of installation files is missing. I clicked the Learn more link and eventually ended up downloading the 2014 version from the website just to have the exact same message.
When I view the Digital Signature tab of the kis18.104.22.16851en_5450 it tells me that "One of the countersignatures is not valid. The file may have been altered.". The only countersignature is the COMODO Time Stamping Signer. When I view the certificate inside the details of the COMODO signature it says "The timestamp signature and/or certificate could not be verified or is malformed.".
I have tried running as administrator, using the troubleshoot compatibility tool, deleting toolbars, going into the task manager and shutting down all non-essential processes, nothing seems to make this install.
What do I do?
Here is the GetSystemInfo report:
