Have anyone got this message?

I downloaded lates beta 20, installed Air and added it  as SDK - then i go this message. Tried to delete SDK and go back to SDK Air 19 - but same message appeared. 

Did not try to reinstall  Air 19 - because i did not know how to uninstall Air 20

What shall  i  do and how to make this work again?

‌Same here. Uninstall Air 20 by going to Applications/Utilities and run Adobe Air Uninstaller in Mac. Then reinstall Air 19 and thing will be back in business

hope Adobe fix this problem. As far as I know, even Adobe Download Manager stop working with Air 20 beta (all versions to November 11) and app that use Air like Eathnrowser also stop working as well
