In MYOB Accountants Enterprise (AE) Series 6/8, you may experience the error "I/O Error in TCF file" when opening a Tax return from within AE.

This issue may occur where the Tax Program Path in the Tax Settings refers to an incorrect location. To resolve this error, you'll need to update the Tax Program Path in the Tax Settings.

Before you begin, you'll need to know the location of System Release.
