If you have uninstalled and reinstalled but still see errors, leftover registry entries might confuse Crystal Reports.
Warning: Editing the registry incorrectly can damage Windows.
Scenario: The barcode appears visually, but scanners (laser or imaging) reject it.
Causes:
Solutions:
Sometimes the report stores an absolute path to the old DLL. To fix:
Open a Command Prompt (Admin) and type:
reg query HKCR\CLSID /f u25idautomation.dll
If you see a CLSID returned, the DLL is registered. If not, run:
regsvr32 "C:\Program Files (x86)\IDAutomation\Code 25\Barcode\DLL\u25idautomation.dll"
If you distribute an application that uses Crystal Reports with u25idautomation.dll:
Ensure you have downloaded the appropriate UFL package from IDAutomation. The file u25idautomation.dll is typically found inside the download package. u25idautomation.dll crystal reports
If you receive this error when opening a report:
The installation path depends on your operating system architecture and your version of Crystal Reports.
For 32-bit Systems / Crystal Reports (x86):
Place the file in the Windows System directory:
C:\Windows\System32\ If you have uninstalled and reinstalled but still
For 64-bit Systems:
If you are running a 32-bit version of Crystal Reports on a 64-bit machine (most common), you generally need to place the file in the SysWOW64 folder:
C:\Windows\SysWOW64\
Note: Some newer versions of Crystal Reports may look for UFLs in the Crystal Reports installation folder (e.g., C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports\...), but the System folders are the standard location for legacy UFLs.
