Hi Guys,
The only way I got around this issue was to set up the odbc connection as instructed on a 32 bit machine, and then then copy the filemaker file to the 64 bit machine, which works a treat.
Hope this helps!
Sorry Nick, I don't have an answer for you, but I have been struggling with the same problem all evening!
If anyone can help, please do - I need to edit live MYSQL data in fm pro 11 app.
