Help !!

I use VB 6.0 and Crystal Report 8.0, I use Crystal Report to generate .rpt file and then add it to VB, everything runs Ok !
but after I make the .exe and packaged then installed on the machine that don't have the Crystal Report installed. I run the ap, it runs ok, but when I try to view the report , I got nothing but empty viewer and error message popup said 'Physical database not found', can any one tell me what I did wrong.


Thanks in advance !
