Is this an error or intentional?:

IfFileExists "$EXEDIR\App\GTK\bin\*.*" "" UniqueGTKDIR
;=== Shared GTK Directory
StrCpy "$GTKDIRECTORY" "$EXEDIR\Apps\GTK\bin"
Goto EndINI

Missing 's' in IfFileExists

at home (where i have gtk installed already) it works fine. at school, where there is no gtk, it's telling me it's missing a dll and it won't even open.
