I downloaded the 1.9.0 beta build 36 and out of the box the avrdude.exe cannot be found while attempting to upload (exception with unexpanded '{runtime.tools.avrdude.path}' text) . I am on Win10.
I have added 'runtime.tools.avrdude.path=.' to the preferences file and it worked.
However, that entry disappeared after closing the IDE (preferences.txt got overwritten) but next time all worked.

It works fine for me, also using Windows 10.

You need to close the Arduino IDE before editing preferences.txt. However, you shouldn't need to add that entry to preferences.txt to get the Arduino IDE working.
