I might have made a big mistake by updating MikTeX after I updated TeXstudio a few weeks before. Now when I try to Build my file, I get the error: "Sorry, but xelatex.exe did not succeed. The log file hopefully contains the information to get MiKTeX going again:"

The indicated log file says this (several times):

The log file hopefully contains the information to get MiKTeX going again:


I truly hope that I don't have to uninstall and reinstall Texstudio, because I fear it will be a nightmare trying to get everything set back up again the way I have it now.

Thanks in advance for your assistance!

  • In TeXstudio, you can create your on profiles in the Options menu. You have only to save your own editor's macros to restore them afterwards. I use pdflatex, (re)-installing TeXstudio is not the main concern, normally issues come from updates from MikTeX.

  • @FHZ I don't think I have any editor's macros, at least not that I'm aware of. I assume those would be something I created myself? Also, are you saying all I need do is save profile, uninstall Texstudio, then reinstall it and load the saved profile? Will that get me back to where I used to be?

  • Yes, your own editor's macros are the ones you created yourself using the menu named macro. They are not the \newcommands (which are also a subset of the set called macros in LaTeX). I recently installed/uninstalled/reinstalled versions 3.1.2 and 4.2.2 and I had no issue regarding TeXstudio. What I can't say for sure is what is causing or why are you having the presented issue.

  • OK, I guess I'll have to just give it a shot. The issue only arose immediately after I updated MikTeX. It clearly has something to do with that. Perhaps Texstudio can't find Miktex now, or some such thing like that. Fingers crossed. Thanks much.

  • One week ago I had a similar issue after updating MikTeX. I used TeXstudio 3.1.2, I tried version 4.2.2. Issue was still there. I revised the upgrade in MikTeX. Reinstall TeXstudio and it worked, but once again, that's not the solution of your issue. The main idea is that TeXstudio is only an editor, it depends of your LaTeX installation (given by MikTeX), not the opposite.

It seems I hadn't actually updated MikTeX, but rather, I had installed a newer version, MikTeX 21.3 to be precise. What I did to fix the issue is, I updated MikTeX through the MikTeX console. Then after reopening TeXStudio, everything seems to work fine, just like it did before installing the newer version of MikTeX.
