I need to set "InstallDir" in a function. but it wont let me do that is there a way i could use a var and then change that in the function ?

Thanks, Tom.

The variable it uses is $INSTDIR, and you can modify $INSTDIR in function or section.

k, how can i define it different in 3 functions ?

It's a variable, so you can change it like any other variable. StrCpy, ReadRegStr, ReadINIStr, ...

Section MainFiles

StrCpy $INSTDIR "$PROGRAMFILES\Foo\Bar"

SetOutPath "$INSTDIR"
...

SectionEnd

Errr... You're writing an installer in NSIS, and you're asking what language it is? It's NSIS script, duh.

Please read the documentation for information on what commands exist and what they do:
