DiffEngineX Crash Response

We are sorry that DiffEngineX crashed.

  • To avoid problems it is recommended that you do not modify, open, save or otherwise work with Microsoft Excel workbooks while DiffEngineX is in the process of comparing. If you must open a new spreadsheet, please do so within Excel, rather than by double-clicking a spreadsheet on your filesystem.
  • When comparing very large worksheets, DiffEngineX can take tens of minutes. Often a slow comparison indicates that the user has not sorted the worksheets first in Excel (see Excel's Data menu or tab) and then saved them, if appropriate. Align Rows may need to be selected.
  • Although DiffEngineX works with all versions of Excel from 2000 to 2010, for best performance we recommend using Excel 2002 or later.

If DiffEngineX continues to have problems, please do not hesitate to contact us.
