This version of GIMP is very unstable and only for testing or discover new features. Download link:

For instructions, extract the contents of "gimp-2.9.1-portable_20120622git.7z" file and read "Readme - Portable Instructions.txt" file.
If you have 32 bit libraries installed on your 64 bits system, you can run this portable version in "very limited way" on 64 bits Systems. That is, many things in GIMP "will not work correctly"*******On 64bits System only GEGL filters are loaded and multiple failures can occur*********


This portable includes LJFHutch brushes set:

and G'MIC plug-in can be used on 32 bits systems.

Thank you for sharing.
Brush set is very interesting.
