I upgraded CRD4 to CRD5. Now my reports wont run. Error message is 'If you are using CRD for CR9.xx, you must make sure that you have CR9.xx Developer or Advanced installed. I have CR9 Developer installed. My reports ran fine from CRD4. Any ideas, thanks in advance.

Try reinstalling Crystal Reports again. Also Try to go to Housekeeping in the options menu and refresh the CRD connector.

Do you have the latest service packs and hot fixes installed for CR 9?

yes, i do have all hot fixes and updates. I will try reinstalling CR9. thanks

Thanks John for your help
