Passing command line parameter to MUI_FINISHPAGE_RUN

I am having a lot of difficulties with passing a parameter to my program, for MUI_FINISHPAGE_RUN.

MUI_FINISHPAGE_RUN is used to specify an application run after the installer finishes. I would like to pass one long parameter to this, which are in quotes.

I have tried:
!define MUI_FINISHPAGE_RUN "$\"$INSTDIR\${PRODUCT_EXE_NAME}$\" $\"$INSTDIR\Sample\filename.type$\""

!define MUI_FINISHPAGE_RUN '"$INSTDIR\${PRODUCT_EXE_NAME}" "$INSTDIR\Sample\addresses.ism"'

But nothing seems to work. The program doesn't even get executed.

Can anyone help this this at all?

!define MUI_FINISHPAGE_RUN_PARAMETERS ...

It's just under MUI_FINISHPAGE_RUN in the Modern UI manual 😛

Wow. Did not expect such an easy solution.

Thanks Stu!
