Adobe AIR v 17.x & 18.x problem. Impossible to uninstall?

So my Secunia program informs that these versions need manual updating. I installed the new version Adobe AIR 20, but I am unable to install the previous versions. Used control panel to delete everything, manually deleted everything in C:/Program Files, Program Data, Commonfiles,

used CCcleaner to clean the pc and used REVOinstaller to get rid of remnants. It appears that I still have these outdated Adobe AIR installed somehow, I tried reinstalling and uninstalling in command prompt with "adobeairinstaller.exe -uninstall" command, but I always get failed.
I need some help with this. If I'm gonna run Adobe AIR 20 I should have previous versions uninstalled, and one would think it be fairly easy to uninstall program.
