Hi Johan,
I, too, have been using pp + innosetup for many years, so that is not the problem. BTW my apps are Perl/Wx based.
Seemingly I'm not recognizing the advantage in using pp *in addition* to InnoSetup. What is the point to use InnoSetup just to transport *one single exe*? If you work with the unpacked stuff, you could provide separate Windows executables calling the Perl interpreter to run the Perl scripts. Such a wrapper is only tens of KiB. Perl with libs etc, are shared then. Find the (trivial) sources of such a wrapper at https://oliverbetz.de/pages/Artikel/Portable-Perl-Applications Not yet prepared for a gui version but this shouldn't be a problem. Oliver
