Gimp 2.6.x installation error occurred
Hello.Do you have a Gimp 2.6.x installation? You should have it, if you do not then download it. This error sometimes occurs if Gimp 2.8 find the old Gimp 2.6 dll.You need to do a search for libjpeg-8.dll and see what comes up. After that you need to Allow Gimp 2.8 to remove Gimp 2.6, or you can just delete it by yourself. After that is done, you should reinstall Gimp 2.6 and the problem should be solved. I hope that this helps.
