We got the developer version which comes with 5 user runtime licenses. VFP client only view the generated rpt files. Even we run it on the server, there are only a few (less than 5) processes accepting the requests to generate report. Only one process can actually call crytsal report at a time to generate the rpt file, while other processes can run logic in VFP (which is the most time consuming part) but not calling crystal (which is the least time consuming part). I don't know if I still need another licenses for this setup? Thanks for your comments.
