Sketch will not Upload from IDE 1.6.3

I just downloaded IDE 1.6.3. Sketches that uploaded in previous version will not upload, now. I received the following error message:

avrdude: error at C:\Program Files (x86)\Arduino\hardware\tools\avr/etc/avrdude.conf:332: programmer type must be written as "id_type"

Please help.

I would suggest you first uninstall Arduino IDE and then install it again..
