Troubleshooting Data Matrix 2D Barcodes in Crystal Reports

• This page lists some common problems (and solution) with barcodes in Crystal Reports

• You receive one of the following error messages when running the report:
  UFL 'u2lcom.dll' that implements this function is missing.
  The Visual Basic UFL that implements this function is missing
• Solution: Install the necessary UFL files.

• Crystal Reports reduces the size of large fonts when exporting or printing via PDF. This behavior is by design, but not desired with barcode fonts.
• Solution: Edit the registry to add the following key:
  HKEY_CURRENT_USER\Software\Seagate Software\Crystal Reports\Export\Pdf Add a DWORD value with the name ForceLargerFonts and change its value to 1.

• If your barcode is showing as gibberish text instead of bars, the most likely cause is the fonts are not installed.
• Solution: Install the font files.
  To install, copy all files from: C:\Program Files\BarCodeWiz\BarCodeWiz Data Matrix Fonts\Fonts\
  To: C:\Windows\Fonts\
• Ensure that Crystal Reports is NOT running during font installation. Otherwise, a restart is necessary.

• If your barcode is blank, there may be an error in your text input.
• Solution: See this tutorial on how to use the Data Matrix formulas in Crystal Reports

This might be caused by Data Execution Prevention mechanism which is included in the Windows OS.
