• When attempting to Export Read-Only, the following message:
  

  Error accessing offline instance. Please check it is not currently open.

  The underlying cause is a 260 character path length limitation in Windows.

  While Pentana will run where the path to vision.exe is shorter, some functions may fail if there are other application files with a longer than permitted path.

  You should aim for a path to the application of 199 characters or fewer.
