libtiff3.dll missing when using Separate+ plug-in for Gimp 2.8

Posted: 6th August 2012 by Seth Killey in Apps

This is more of a note to myself, but if others benefit all the better…

We use Gimp for staff members who need to create CMYK images, but don’t necessarily need full blown Photoshop.  There is a nifty little plug-in called Separate+ which allows you to accomplish this feat.  When porting over from Gimp 2.6 to 2.8 I got an error after adding the Separate+ files to the plug-ins folder.  Basically the error was complaining about libtiff3.dll missing.  On another computer using Gimp 2.6 I was able to grab libtiff3.dll and copy it to the GIMP 2\bin folder on the version 2.8 installation to fix the issue.  When it was all done I had the following in the plug-ins folder (GIMP 2\lib\gimp\2.0\plug-ins\):


and in (GIMP 2\bin\)

    I had the same problem. Your solution works great. Thanks.

  2. Vinay says:

    Thank you very much. Same problem, but fixed in the same way.

  3. Max says:

    Had the same problem with version 2.8 but after following the instructions, the dll missing error no longer shows but I get 2:

    separate.exe – Application Error
    The application was unable to start correctly (0xc000007b). Click OK to close the application.

    Errors… aaah 🙁

      I have still the same problem. On another site I read about a problem, when you are using 64-bit System. This guy replaced 2.8 with 2.6.11 and then it worked (he wrote).
      But I will wait on a solution for a 64-bit system

      • Arold says:

        I had the same problem as you Max and Ruedi.

        In addition of the “libtiff3.dll” file found on this site, I used the .exe files from “” instead of the ones from the “” (see the separated+ web site) and I don’t have the errors anymore.

        Give it a try.

      • Mishka says:

        Yeah, I’m working on a booklet for print, and it needs to be in CMYK color space, but it needs to be in pdf format. I can use Gimp 2.6.11 to export it as CMYK in TIFF format but not pdf, if I open the TIFF in 2.8 I can export to pdf but it reverts to a default RGB color space when I load the image.

      • DS says:

        Thanks! I just installed 2.6.11 and Separate+ works just fine with it.

    • Kyle Mitchell says:

      It’s 2016 and I wanted to update anyone reading this who has any issues and say that the solutions provided here still work. I’m nearly computer illiterate, but I managed to get Separate+ to work on Windows 10 for Gimp 2.8. The link for Separate+ at the top of the page still works. I had the .dll error, then the (0xc000007b) error, and as someone stated earlier this could be fixed by 1) downloading the .dll file at the top of the page then copying into your bin folder and 2) downloading the file in the link Seth provided then copying into your plug-ins folder.

      • Josh says:

        Am still trying to install separate+ but get 4 error messages. I’ve followed the above already… It says the following are missing from my computer.
        Where can I find:

      • Sander says: works with Windows 10 64 bit. The Seperate 0.5.9 alpha 64 bit does not work on windows 10 64 bit 🙁

        Good luck!

      • Jacki says:

        Thank you! That’s exactly what I needed to do, and I’ve been looking around for nearly an hour to figure it out…much appreciated!

  4. JanaKirsten says:

    you reaaally helped me!! I was working on that error for 2 hours or so… Thanks a lot!!

  5. Craig says:

    Thanks for this post simple fix.

  6. Max says:

    Short, clear, and full answer on how installing seperate + for windows and fix the dll problem. You’re great, thanks.

  7. Roy says:

    Thanks for the quick fix. Best instructions on how to install separate+

  8. Val says:

    I have the same problem but when I copied and pasted the file into the correct folder it still showed up that I was missing it =/

  9. Max says:

    Thanks, that helped!

  10. Jason says:

    Thank you very much for both providing the file and explaining what you did…documentation in the GIMP plugin registry is pitiful.

  11. Paul says:

    Arold’s additional input was the key for me. Running 64 bit Win 8 and all works great now. Thank you Seth and Arold!

  12. Edgardo says:

    Thanks a lot for your help! I got an error after adding the Separate files to the plugins folder

  13. Thank you! I wonder why 2.8 doesn’t come with this dll?

    I’m still unable to open a CMYK file though. I think I still need to muck around with getting some icc color space profiles or something?

  14. Gabriel says:

    Worked like a charm, thanks!

  15. Slobodan Mamula says:

    you’re a star – thanks

  19. Kai says:

    I can’t thank you enough! You’re literally a lifesaver!
    When there was still another error after the libtiff3, I followed your additional instructions from the comments and got rid of all problems:

    “In addition of the “libtiff3.dll” file found on this site, I used the .exe files from “” instead of the ones from the “” (see the separated+ web site) and I don’t have the errors anymore.”

    Superstar. Thanks, pal.

  21. I have installed seprate plug in and it is working fine with GIMP ver 2.8. But when I export picture to save JPG/TIFF than -CMYK add in file name auto.
    How can this disable so that original file name would be intact.

    Please help..

  24. Kathleen says:

    Thanks!!! I’ve gotten the plugin working now, after I got the three files in the plugin folder and the dll in the bin, just as you stated up above. YAY!!!
