Hi Ian
I followed these steps and it works on my own computer. I installed from the latest SAP Patch level Packages folder, SAP Business One 9.00 PL08 UPGRADE\Packages\Crystal Server Integration\BusinessobjectsRuntime32\setup.exe followed by SAP CRAddin Installation\SAP Business One Crystal Report Integration Package.exe.
My computer is Windows 7 32bit working as SAP Server and Client, Crystal Report version 14.0.4.738
