MiKTeX and proTeXt ⇒ "Internal error" after MikTeX update -- with workaround

[tjaenare]

Hello!
After the last MikTeX update the process was terminated prematurely and the distribution was a mess due to problems with the anti virus software.

Switching anti virus off, I installed MikTeX from scratch on my Windows 7 (32) machine with the latest basic MikTeX version. The installation went without any indication of problems. I compiled my LaTeX document only to realise that still there is a mismatch between biblatex and biber versions. So, once again, I started the update, which indicated that some core elements needed to be replaced. The process again went without indication of errors. So far, so good.

Once, however, I restart the update wizard in order to download the deleted files and update the others, I receive the message: "Sorry, but something went wrong: MikTeX encountered an internal error". The update.log does not give any further details, either. It does not matter whether I continue with the admin or the user version of the update, the error occurs with the same message in both.

Does anyone know how to either fix the error or circumvent it? Would specifically delete the existing and download the updated biber and biblatex file in the package manager do the trick?

Thanks a lot in advance...

I guess the underlying reason is the same as for this one!?

Same problem... >"<
Tried to reinstall MikTeX 32 and 64, but the error resisted...
Reading the attached link, but still don't know how to fix the problem...orz

I know it is not the best solution in the longer run, but at least I got MikTeX to work again late yesterday night:

Had a fresh install of the distribution. Then I compiled my LaTeX document in order to install the missing packages. For me, the crucial point was the mismatch of biblatex and biber versions. So, I started the package manager, deinstalled the miktex-biber.bin, restarted the computer, and had it manually installed via the package manager again.
If you have other packages causing this conflict, this post might give you some other idea how to work around the issue while waiting for the update:

Good luck!!

I also only have biber/biblatex error...

After I start searching how to install TeXLive, I found this one:

I follow "Werner A."'s answer, and MikTeX starts to update... Hope my biber/biblatex works after updating...

Thank you for the update!!
Unfortunately, this did not work out for me. Updating worked as over the previous days: the first round worked without problems, the second failed with an internal error.

I keep fingers crossed that it works out for you!

I switched from MikTeX to TeX Live a long time ago and I'm very satisfied with TeX Live. If you don't get MiKTeX working, TeX Live is still a fine option.
