I have developed one application in VB6 and SQL and Reporting in Crystal 8.0. As in my pc software is running ok but in Client pc it is not running and giving me error that 'Cannot find database dll' and when i install crystal 8.0 on then machine it will running ok.
Depending on your Operating System, look for a Crystal folder under your Windows folder on your own machine - this should contain lots of dll's. Try copying that onto a client machine in the same location. You may need to register the dll, if you can find the right one, or else you may need to copy it into somewhere like C:\Windows\System - sorry to be a bit vague but I can't quite remember.
