New Windows installer for GIMP 2.8RC1
A new plugin installer is available for those which are already using GIMP 2.8 under Windows, since the previous one was not working (only a 32bit version, as the previous one). It can be downloaded from here. You should probably uninstall the previous version from the control panel first.
(Note: this is not a new version of the plugin, non-Windows users can use the sources and recompile for the new GIMP 2.8, everything should work as ususal - at least it does for me…)
