I needed to do some Magic Workstation patch update again for the newest MtG set, Oath of the Gatewatch. Of course Google is my friend in getting the info and file to do it and I will also gladly share with you guys. I have found this resource from the MTG Salvation forums, posted by username Kovukono. He posted the complete zipped file with the patch, pics and theme.

After downloading, you just add the new set via the Add/Remove sets tab with expansion initial ‘OGW’. Follow the next steps and you are done. For the card pics, just copy paste them in the Pics folder of the Magic Workstation program.
Enjoy building and creating decks with the new Oath of the Gatewatch set!
