gtk

My seccond ask is:

how can i check if gtk is installed on the users computer

I'm not able to specifically help you because I don't know what gtk is 🙂
Generally, if it has a default location where it is installed, (e.g. system directory) you should check with something like IfFileExists '$SYSDIR\gtk.dll'.
Furthermore must exists one or several registry records where you should trace if it is installed and the exact location as well.

gtk is a gui how qt or WxWidgets do you know?


i will do it so:

if gtk (lib) not installed so comes a window where stand:

You requierd GTK for this programm



sry for my english😉

Gaim installs GTK with NSIS. You can check out its script.
