can innosetup be used without installation?

[Elhanan Maayan]

hi, i'd like to be able to use inno setup as part of a maven build 

and i don't want to start installing it on every machine that needs building it

so i thought about maybe taking the entire package and make it a maven artifact in our nexus 

and simply download, extract and use it to compile the setup at  the end of each build 

(the main intent is simply create a self extracting exe to be used in signtool

Yes, you can run the Inno installer with /PORTABLE=1 to make it skip external installation steps.  You can either do this as part of your build pipeline directly or repackage the individual files that you care about.

Note that you'll also have to use the /S parameter to the compiler to provide the signtool definition during the build, since the IDE settings will not be available.
