First, thanks for this current GIMP Extensions Pack for Windows (http://registry.gimp.org/node/27656). However, after running GIMP_Extensions_v2.8_latest.exe, my folders only had the following installed:
Did I run the installer incorrectly?
Only checked options are installed.
There is no installation of brushes.
If I look at your list only a few plugins have been installed, no scripts.
