Adobe Fill, Crash repeat
Adobe reader can fill .PDF forms but the form has to be created with the fields to fill in. If in doubt do a google search for “example fillable PDF” you can download it and fill to verify.
Adobe reader CRASHES when filling some forms. to fix open Adobe, Menu, Use OLD reader. Adobe will restart and, in my test case, stopped crashing.
If your form does NOT have fillable fields, you can use the ONLINE PDF to Word converter that is published by Adobe. Why would Adobe charge $ for a program that converts PDF to Word and then give away the same service online for free?
