--- Comment #8 from Anastasius Focht focht@gmx.net --- Hi JB,
could be an interrupted download.
Just do as it says: rename or better remove the corrupted download and retry.
--- snip --- rename /home/backes/.cache/winetricks/vcrun2019/vc_redist.x86.exe and try again. --- snip ---
If it persists try to manually download by different means using the URL and place the .exe in that cache folder path.
Not that it would help in this particular case but if a download link is broken (404) use a newer winetricks script version:
--- snip --- You are running winetricks-20200412, latest upstream is winetricks-20201206! --- snip ---
