Greetings. This is my first post here. I'm developing an app for use
by people with very limited computer skills, so I am trying to make the
installation process as easy and simple as possible. I plan on using
command-line curl (under program control of my app) to download the
initial installation of the app, and to download software updates as I
make them available.
My user base will be running Windows, anything from Windows 7 through
Windows 11, and either 32-bit or 64-bit.
Since prior to Windows 10 curl.exe didn't come installed in Windows, I
can't depend on curl always being present, so I need to provide curl as
part of the installation. I would prefer to install and depend on just
one version of curl, namely the one in https://curl.se/windows (curl for
32-bit). For my purposes it's not important to get any speed boost by
using a 64-bit version on 64-bit machines.
In my testing (only under Windows 10), it appears that there are only
two files necessary from curl-8.2.0_1-win32-mingw.zip\bin to run
command-line curl, namely curl.exe and curl-ca-bundle.crt (since I'll be
downloading from an HTTPS site). It doesn't appear to require libcurl.dll.
Here is an example of how I will use curl:
curl -L
"https://drive.google.com/uc?id=Blb4xtM-RvXqpKwqZuc5OYw4zMlD1U-uD" -f -s
-S --stderr DL.ERR -o TEST.TXT
My questions are:
1. Is it correct that these are the only two files I need to install to
run command-line curl?
2. Will this version of curl run on all versions of Windows, from 7 to
11, and in all cases either 32- or 64-bit?
Thanks very much. / Rav
