There are no installation instructions. I downloaded the Windows 64-bit version. When I run the executable from my download folder I get this popup error message: gmic_gimp.exe - Unable To Locate Component This application has failed to start because libgdk-win32-2.0.0.dll was not found. Re-installing the application may fix this problem. Apparently I have to "Rate this Project" in order to submit a review. Since I haven't been able to use it, my "rating" is meaningless.
