Jay,
If it's anything like FRX2Any then you have to check the Debug Info checkbox in the Project Information form prior to compiling. These tools run execscript() on the non-compiled report code which doesn't exist unless the Debug Info checkbox is checked.
If you don't want to do that you have to program around it by including the ability to export the report (from the exe) to a file on disk and then fill in the reportcode from data stored in the exe and then run XFRX on that exported report. (I have taken this approach).
