I updeted yesterday all my packages in Miktex (after I got problems with longtable, which are not importent for my problem here). After this I got for my document a lot of errors. Before the package-update i did not get an error. Searching the problem, I found Documents depending on etexcmds not compiling. So I updated all packeges using Miktex, but still the error is there. Could somebody understand the error ? Is this a bug of the new version in the oberdiek-bundle from 09.12.2019 or an other package?

Thanks for help.

Hereby a small example:



Ends with 2 errors, the log-file shows:

    Please make sure your miktex is fully up to date as both admin and user. Several packages have been relocated recently and miktex does not always like that. We can see from the log that you'll need update as both admin and user (hint: the AppData lines). The latest iftex I have on my system is from november 2019!!

  • The example compiles fine for me on a MikTeX system updated this morning. As daleif said you should update MikTeX in Admin and User mode. In order to keep the on-the-fly installer happy you should also run Tasks > Update package database in the MikTeX Console in Admin and User mode.

Thanks for the answers.

Here I will show my final solution and the way:

1) I tried to update the packages in Miktex Console in adminitrator mode AND in user mode. For both I tried to update the package database first (see Tasks - Update package datbase). After this I update all packages --> both mode have shown "There are currently no updates available" --> do not solve the problem because the iftex-package was not updated for the user (look into the log-file after compiling the tex-file shown above once again)

2) Second I tried do to this with CMD (as Admin and without). If you normally do not use the terminal, see https://docs.miktex.org/manual/mpm.html .
I could uninstall and install packages in admin mode (CMD must be started as ADMIN!!!). But for user mode ("mpm --verbose --uninstall iftex") it did not work. On CMD I found:

Sorry but "MiKTeX Package manger" did not succeed. The log file hopefully contains the infomration to get ...

The error in logifle shows:

**--> no solution, the package was not updated **

3) I searched the sty.files "iftex.sty" normally used for admin (C:\Program Files\MiKTeX 2.9\tex\generic\iftex) and copy this to the place where all the sty-files for the user are (C:\Users\NUTZER\AppData\Roaming\MiKTeX\2.9\tex\latex\iftex) --> This solves the problem.

Maybe there is a more efficent solution (if someone knows, please give a request), but i can go forward with my work.

Hopefully this will help someone (no professionals like me) saving time (some hours)...
