Crystal Viewer error "This field name is not known"

51 Views

I have MAS500 with crystal 10 that runs a report from a view in a SQL data base and it ran fine when only MAS500 and ABRA were installed on the terminal server. Then we installed a new product CribMaster that also uses Crystal 10. After CribMaster was installed we got the error "This field name is not known" from Crystal viewer. The report has a selection parametar . I feel that there is a dll file that got over written, but do not know which one. I can run the report from Crystal OK, but not from within the application.
