I have an assembly, which export data to Crystal Report. I registered it and use DOTNET in PHP call function, when I tried to load any report, I got this error:
Unknown Query Engine Error Error in File C:\Users\...rpt: Unknown Query Engine Error
When I call the assembly from my standalone EXE, it works fine...when I call the same report with the same data (and the same code to generate the report) from PHP, I get the unexpected query engine error.
Please help me! Thanks.
