#2484 Compability MikTex

[Anonymous]

I want to Install the newest TeXStudio with MiKTeX 4.2.
The Installation of MikTex 4.2 works.
But after installation of TeXstudio 3.1. I get Errors with the first Run:
tart process: initexmf --enable-installer --dump-by-name=pdflatex --engine=pdftex
2021-04-08 16:22:20,723+0200 ERROR pdflatex - C:\Program Files\MiKTeX\miktex\bin\x64\initexmf.exe did not succeed; exitCode: 1
2021-04-08 16:22:20,723+0200 ERROR pdflatex - output:

Sorry, but "MiKTeX Configuration Utility" did not succeed.

If I try it with MikTex 2.9 it works.
How do I get MikTex 4.x to work?
