powerpoint crashes when entering text

this issue only happens on boot camp installs of windows. apple pushed an update which screwed up the keyboard options in powerpoint, so it crashes. does not affect excel or word.

• in powerpoint, go to File > Options > Language

• under the heading keyboard layout a hyperlink which says "not enabled" will be present

• click on the hyperlink and select English "US" keyboard

• close the options, close powerpoint, then reopen the file.
