  2. Try and run a report with the registered UFL in a custom application or through enterprise.
  3. Try and use the UFL in the Crystal Reports designer.


If a Crystal Reports UFLs created in Visual Studio .NET has a dependency that needs to be loaded from their own specific directory, those dependencies will not be found and loaded by Crystal Reports.


  1. Place UFL's and its dependencies into the same directory.
  2. GAC the dll as follows:
    a) Copy the UFL dll into The correct bin directory. For Crystal Reports 2008, this is C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86
    b) At the .NET command prompt type; gacutil -i "C:\<path to your UFL>"
    This should result in the message; "Assembly successfully added to the cache."
  3. Run REGASM from the command prompt:
    Type regasm codebase "C:\<path to your UFL>"
