One of Wampserver's features is the ability to run the same local site with different versions of PHP simultaneously, using FCGI mode.
This is used a lot by users who want to update old sites running an old version of PHP, and these old versions of PHP require old versions of C++ dependencies.
Even if these old C++ versions are EOL and no longer supported, they are still functional.
The addon installers for older versions of PHP (or Apache or MySQL) don't check whether the necessary VC++ is installed.
The only way I've found to avoid problems is to check that these older VC++ are installed during Wampserver and Aestan Tray Menu updates.
If you don't need them, fine! But you know very well that 99% of users don't read popup texts and click on the Next button without really knowing what they're doing.
So it'll stay as it is.
What's more, under the link given :
All VC++ packages are on
https://wampserver.aviatechno.net/section "Visual C++ Redistribuable Packages" See: "Best way to install Visual C++ Redistribuable Packages"
Use this installer, which installs ALL VC++ dependencies in a single installation and removes obsolete or unnecessary files. You'll only have to do this once, and then update VS17 if necessary.
