I am running FlashBuilder 4.6. I created a folder C:\Program Files (x86)\Adobe\Adobe Flash Builder 4.6\sdks\4.16.1
I copied in the 4.16 Flex SDK I then copied the AIR compiler v32 on top of that (overwriting files as needed). This is what I found as the proper way to do the upgrade from - https://www.andygup.net/how-to-upgrade-your-air-sdk-in-flashbuilder-4-6/ Paul R.

Flex has an air-config.xml with different library-path than standard AIR SDK. IMO, re-installing with the right AIR version has been used more than other options. IIRC, there is a script to use to upgrade as well.
