First, make sure that you copied ALL the files, not just the .exe file, that the compile creates. It also creates a .crf file.
If that is not the problem, then go to the machine where you wrote and tested these reports and make sure you can still execute it from within crystal reports. Then compile the report and copy the files to another directory and try to execute the .exe file from the same machine where you can execute it from within crystal reports.
If this works, then test it from another machine. If you cannot get it to work from a different machine, make sure the workstation has all the services setup to run the report - for example a crystal report on a btrieve database will not execute unless the workstation itself has the btrieve engine installed, even if you compile it.
Let me know what you find.
