Comprehensive Guide: Resolving u25idautomation.dll Errors in Crystal Reports

Step 6: Test with a Minimal Report

Create a new Crystal Report with a single formula:

// Test Formula
EvaluateAfter(PrintingState);
// Replace with actual function name from your UFL documentation
// For example: UFL IDAutomation_Code128("TEST123")

If that fails and you see u25idautomation.dll again, the issue is global. If it works, then the original report has a corrupted reference. Recreate the barcode formula from scratch. u25idautomation.dll crystal reports

Step 4: Place and Format the Barcode

  1. Drag @Barcode_Code25 onto your report section (e.g., Details or Page Header).
  2. Resize the field to be at least 2 inches wide.
  3. Right-click the field → Format Field → Font → Select IDAutomationI25 (or C25 for Code 25).
  4. Set the font size to 14pt.
  5. Run the report. Scan with a USB barcode reader.

Common Use Cases

  • Warehouse labels (product IDs, lot numbers).
  • Library systems (member IDs on cards).
  • Industrial manufacturing (work order tracking).
  • Shipping manifests (where Code 25 is still legacy-supported).

4. Permission Issues

If the DLL resides in a folder where the Crystal Reports runtime user (e.g., IIS Application Pool, Windows Service) does not have Read & Execute permissions, the load will fail. Comprehensive Guide: Resolving u25idautomation

6. Reinstall the Barcode Software

Download the latest version of IDAutomation Native Barcode Generator for Crystal Reports from the official IDAutomation website and reinstall. This will: If that fails and you see u25idautomation

  • Place the DLL in the correct location.
  • Register it automatically.
  • Update any dependencies.

Official Licensing Path

  1. Buy the license from IDAutomation.
  2. They will email a license key or a full, unlocked DLL.
  3. Replace your trial DLL with the licensed version. No formula changes needed.

Best Practices for Deployment

If you distribute an application that uses Crystal Reports with u25idautomation.dll:

  1. Include the DLL in your installer – Do not assume it exists on the target machine.
  2. Match bitness – A 64-bit application using the Crystal Reports runtime (64-bit) requires the 64-bit version of u25idautomation.dll.
  3. Register properly – For older Crystal versions (XI, 2008), the DLL may need COM registration (regsvr32). For newer versions (CR for VS, 13.0+), use the IDAutomation MSI which handles registration automatically.
  4. Test in the target environment – Especially on web servers (IIS) where application pool identity may restrict DLL access.

Step 5: Handle Null Values (Production Best Practice)

If your database field is sometimes blank, modify the formula:

If IsNull(YourTable.NumberField) or YourTable.NumberField = "" Then
    ""
Else
    U25IDAutomation.Interleaved2of5(ToText(YourTable.NumberField, 0, ""))
