If you were using the ISPP precompiler version of InnoSetup, you may find that the InnoSetup Action no longer works with the latest 5.4.1 release of InnoSetup.

This is **Not** a bug in FinalBuilder, so please don't report it to as one.

The Authors of InnoSetup decided to integrate the pre-compiler into the official release (which I fully support), however they have chosen to remove some functionality that we use to access the pre-compiler. You will have to use the "Use Command Line Compiler" option... and no progress will be provided for the action (as was the case when not using the command line compiler). This option is available in the most recent FB6 builds and all FB7 builds.

I have asked the authors to re-instate the previous functionality (but not holding my breath based on the response so far).&nbsp;

I have updated and can see the new option, but how do I emulate the preprocessor behavior? I want to define a variable, but how do I do the equivalent of

```
/dMyDir=%rootfolder%\
```

?

I’ve found it easier to just execute ispp from an execute action as the inno setup action doesn’t work for me (can’t find an include file in the same directory as the inno setup script), then you can just pass /d as needed.
