Crystal 2008 install problems with DLL

Hello,

When I try to install Crystal Reports 2008 there was an error message:

Error 1904. Module C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\cr_report.dll failed to register. HRESULT -2147024769. Contact your support personnel.

I downloaded and ran Dependency Walker which highlighted three issues. The first was a missing MSJAVA.dll which I downlaoded and installed. There are now two remaining dependency issues:

Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.

Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.

These relate to LIBOCAHELPERW-4-0.DLL and MPR.DLL.

Please can someone help as this problem seems to stop me being able to upload Crystal Reports to BOXI.

Thank you,

Julian
