Compiling Errors with latest air sdk

Not sure if any is having similar issues but here it is:

Using latest Apache Flex SDK (4.9.1) -- used the installer.

After that I overlayed the latest AIR SDK (did this three times to make sure I did right -- have done multiple times before)

Updated the application descriptor (with 3.7) and -swf-version=20 in compiler settings.

Now I am getting these errors when compiling (compiling completed 100% successfully before the upgrade).

Any suggestions or solutions would be greatly appreciated (note that I require the mx.controls.HTML class as well as the mx List and mx Canvas classes for very good reason).
