C:\Program Files (x86)\Geany\Geany.lnk should not have "Start in:" set

[gigadude]

Invoking C:\Program Files (x86)\Geany\Geany foo.txt for some existing file foo.txt in your current dir (or at any relative path) fails because the link has a "Start in:" value set; leaving this empty makes it work as expected.

I don't know much about NSIS, but I think this is where the shortcut is created, and according to the docs it seems to be set automatically to $OUTDIR, if I understand correctly. Maybe it's possible to use SetOutPath with an empty argument to clear $OUTDIR, then use CreateShortCut to create the shortcut, then set $OUTDIR back to $INSTDIR afterwards? I really have no clue.

The link is not meant to be used from the command line. It was put there for compatibility when the actual binary was moved to the bin subir.

So please use the actual binary, as in C:\Program Files (x86)\Geany\bin\geany foo.txt. This is not a bug to me.

I agree with @kugel- and he already provided the solution.
