I don't think it's a good idea to download random code from a place
called uptodown.com. You should get the code with an established
provenance.

And be careful of app stores like Microsoft and library stores like
NuGet. Microsoft does not take responsibility for them. Daniel
Stenberg had a heck of a time getting an old version of cURL removed
from NuGet. It was uploaded by some random person, and the version of
cURL had 68 outstanding CVEs. See
