What version of FileMaker are you running and which operating system?
And do you have the same issue with the original file using FileMaker Pro Advanced?
Apologies for not replying sooner; I wanted to re-check everything with a new RT, but the result was the same. It stops running and exports a blank FM file (12kb) instead of one containing a single field + data >120kb in size.
FMA 14 and it happens with Runtimes on both OSX and Windows 8.1. Conversely it's fine when I export an FM file runnng the solution with FMA. I'd originally posted a query thinking it was the final code in Inno Setup that was the problem but it occurs with an RT without the Inno Setup stage.
