Delphi 7 and Crystal Reports 10 VCL problem - Error:512 Print Engine not opened. OpenPrintEngine <PEOpenEngine>

Hello,

We are trying to implement Crystal Reports 10 VCL in a Delphi 7 application.

All is ok when Crystal Reports 10 is fully installed on the machine.

But when we try to setup the application at a customer (who of course
hasn't the complete Crystal Reports environment installed) we cannot
run the Print Engine (OpenPrintEngine <PEOpenEngine>)

--> Error:512 Print Engine not opened. OpenPrintEngine <PEOpenEngine>

Please can anyone help me??


The dll´s same folder as the program exe.
