Reverse engineer: Error calling Python function DbSQLAnywhereRE.reverseEngineer (1 reply)

I am migrating from Sybase SQL Anywhere 9.0 to MySQL 5.6.17 on my local computer (WAMP). I can connect to both DBs however the migration wizard fails at the Reverse Engineer stage presenting the following error:

Starting...
Connect to source DBMS...
- Connecting...
