MiKTeX + XeTeX “\char_make_active:n {“20}%” problem and the solution!

You need to update all your packages. The latest MiKTeX package manager seems rather broken. If you use Task > Update Wizard, you’ll probably meet “The update wizard could not be found”

The solution is to open the Update program directly (type “Update” in Start Menu or find miktex-update.exe. I used both the normal variant and the “(Admin)” variant. A couple of updates later it’s finally working!

  3. I had the same problem but didn’t know how to update once I got into package manager. I tried uninstalling all installed packages from within package manager, but that screwed up my MikTex installation badly. I could not uninstall MikTex 2.9 itself even. I’m now reinstalling in a different directory.

    So with that said : can you give the exact set of instructions to update packages?

  4. After reinstallation of miktex 2.9, I still get the same error. I can bring up package manager admin but compiling always fails.

  5. Finally made headway. I opened up a command line, making sure to selected admin privileges (right click on cmd.exe).

    Then through google I discovered the correct updater command:

    mpm –admin –verbose –update

    Now things work again.

    ARGH!

  6. Hilarious — I experienced this problem on another computer, googled it, and found my own solution in the comments. Another tip — the options have to have two dashes, not one, eg:

    mpm –admin –verbose –update

  8. Solution by boris works! Thanks :) However do NOT copy&paste. The dashes are not the right ones ;)

    mpm admin verbose update <input double dashes :)

  9. Reinstall MikTex, same old problem. How often is this going to go on for? Install MikTex 2.9, same error on multiple machines…
