I had this problem as well. The simple answer is to copy them from 9.5. You can do this by going into 9.5 (or 9), and in the file menu, you'll see an option for app files. Open that, then go into the post processor directory and copy the SB ones. Then do the same with v10 and paste those files into the post processor directory. All good after that.

I'm not positive the indexer post processors are working correctly. I used 10 on an indexer job and it turned out very weird. I did it another way and got the job done so I don't know for sure what the problem was. No time to check it.
