Do you still only have Python 2.7 installed? I have no direct
experience with this, so someone with experience should verify this
suggestion. I thought the latest version of orca that did not
require Python 3 was orca 3.5.9. This would mean that either you
need to downgrade to orca 3.5.9 or install python 3.
