Pidgin and external GTK+ package on Windows

[athane]

Every time I install new version Pidgin on Windows the installer always 
installs package of GTK+ in directory of Pidgin but I have external 
package in GTK2-Runtime (downloaded from www.gtk.org). This couses 
problem with theme in Pidgin. Only way to fix it is to remove GTK folder 
in Pidgin and reinstall the GTK+. I do not know why the installer does 
not see the it. I have GTK+ in system variables. It is annoying. Any ideas?
Thank you in advance.
