CURL.EXE runs stand-alone, LIBCURL.EXE depends on LIBCURL.DLL.

Note: unlike other binary executables for Windows they show the official cURL logo as icon, and contain an embedded Application Manifest to protect against DLL redirection on Windows XP and newer versions of Windows NT as well as DLL spoofing alias DLL preloading, directory poisoning, binary planting, DLL hijacking and DLL side-loading on Windows 7 and newer versions of Windows NT!
See curl-7.60.0.patch for the changes applied to the source tree.

Caveat: the statements

There is nothing we can do to prevent against this.
[…]
There is nothing we can do to fix this, it is endemic in the design of Windows.
in cURL’s security advisory from May 30, 2016 are outright wrong: the Win32 function SetDefaultDllDirectories(), introduced with the optional update 2533623 as well as the security update MS12-081 alias 2758857 and available on Windows Vista® and newer versions of Windows NT since then, and the /DEPENDENTLOADFLAG:‹…› option of LINK.EXE, supported on Windows 10 1607 alias Anniversary Update (codenamed Redstone 1) and newer versions of Windows NT, control the DLL search order during run-time.

on Windows Vista and newer versions of Windows NT to extract all files into the specified directory, preserving their paths.

Note: Expand.exe from prior versions of Windows NT ignore the paths and junk them; use Extract.exe from the Support Tools on Windows XP and Windows Server 2003 instead!

Note: switch to Details view and turn on the Path column when you open curl-7.64.1.cab in Windows Explorer!

Installation

Download the package curl-7.64.1.cab and verify its digital signature, then open it in Windows Explorer and extract its contents into a directory of your choice.

Note: be sure to select the binary executables that match the processor architecture of your machine (as shown in the Path column of the Details view)!

Deinstallation

Remove the extracted contents.

I dislike HTML (and even weirder formats too) in email, I prefer to receive plain text.
