Is it a big change to add older vcredist runtimes, like VS2013?

Which we unfortunately have a third party dependency on for one of our applications.

I could even try my hand at a PR if you want.

It's not a huge change, I'd be happy for you send a pull request if you are interested!

The redist for 2015-2022 is all at the same download url and is fully backwards compatible. When installing, if your required version is more recent than the currently installed version, we just always install the latest version.

To support older versions, we will need to allow different download URL's to be provided. This could be done by providing a new constructor in VCRedistInfo, allowing a download url to be supplied (for both x86 and x64). An alternative (possibly cleaner way) would be to create a new class LegacyVCRedistInfo which derives from VCRedistInfo and just overrides the GetDownloadUrl method.

You can find the details of the 2015-2022 behavior, as well as the download links and current versions for older redists at this link: https://docs.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170#visual-studio-2015-2017-2019-and-2022

You may also want to override the InvokeInstaller function, if installing very old runtimes, if the supported arguments have changed. You can usually check for supported command line arguments by doing vcredist.exe -h

Ok, I will give it a go this weekend.

I have added 2010-2013, if you need anything other than that feel free to send a PR
