This is what I have done:

1) Downloaded ProTeXt-3.1.7-061016.exe 22-Jun-2016 16:48 2.2G http://ctan.dcc.uchile.cl/systems/windows/protext/

2) Installed MikTex on C:\Program Files\MiKTeX 2.9

2.1) Executed miktex-update_admin in C:\Program Files\MiKTeX 2.9\miktex\bin\x64\internal

3) Downloaded the last version of TexStudio and installed it on C:\Program Files\TeXstudio

And when I want to run it, it shows that message.

What I have tried:

Installing the same version that is contained in Protex, Tried installing it in program files (x86), googling the problem but not finding anything that helped me (or at least that I understood as help). I have already checked MiKTeX209-jpeg.dll is missing but I don't see how that thread could be of help to me (maybe I am not understanding something). And also installing and re-installing many times.

I am really lost here, please help!

  • 1) Don't mix Program Files and Program Files(x86) installations if you don't want to have a mess. 2) This file is part of miktex-jpeg-bin-2.9 for the 32 bits version, or miktex-jpeg-bin-x64-2.9 for the 64 bits version. Try uninstall and reinstall it with MiKTeX Package Manager. – Bernard Feb 2 '17 at 21:07
  • Hi, Bernard. Thanks for your answer. I started messing with the installations since it alone installed them on different parts: miktex on prgram files, and texstudio on x86. Where should I install them then? On the program files and not (x86)? – Alfonso José Pizarro Ramírez Feb 2 '17 at 22:48
  • I think it should be left where the installer proposes. What I meant is you should not install two different versions of MiKTeX. Personally, I use a dedicated partition and have no problem. – Bernard Feb 2 '17 at 22:56
  • I used the versions proposed in the locations proposed and I had the problems originally – Alfonso José Pizarro Ramírez Feb 2 '17 at 23:55
  • Did you check whether miktex-jpeg-bin(-x64)-2.9 is installed, and does contain the missing .dll? – Bernard Feb 3 '17 at 0:00
