Could be a Friday 13th thing but tried to run Skydemon 3.2 and update to 3.2.1 today and Avast Antivius 2015.10 immediately quarantined the suite of programmes. I see you have changed the update process, so no uninstalling first, but I had to revert to the old method and disable Avast to restore things to normal.

I too suffered a similar problem with my PC. Skydemon 3.2.0 refused to run.  Skydemon 3.2.1 failed to download.  I switched off AVAST and then got skydemon 3.2.1 to download.  I then switched on AVAST protection again and open the Virus Chest.  Skydemon.exe was in the virus chest so I told AVAST to restore it and add it to the Exceptions List.  Hopefully this will cure the problem.
