Downloads and extract the Visual C++ Redistributables.
"""Downloads and extract the Visual C++ Redistributables.
This is useful when working with minidump files as the user may be running
with a new different version of the runtime. This script aims to maintain
a copy of the various versions.
Versions are normally added once I encounter them, in November 2022, I added
a rather large back catalogue of versions.
This requires dark.exe from Wix (http://wixtoolset.org/releases/) and
expand.exe (File Expansion Utility - this comes with Microsoft Windows).
For extracting version 9 (Visual C++ 2008) it requires 7zr and 7za from 7-zip.
Known Limitations:
- No extraction method for Visual C++ 6, 8, and 10 are implemented.
Version 6 and 8 likely would require the ability to extract a MSI.
- Visual C++ 9, 11 and 12 don't extract with nicely named files. For example,
a file is named F_CENTRAL_msvcr120_x64 rather than msvcr120.dll.

How do I extract the 2005 file?

I don't think I have looked into that as I haven't had a need to go that far back.
I try to take a look at in in the coming days.

I don't think I have looked into that as I haven't had a need to go that far back. I try to take a look at in in the coming days.

7zip can see the cabinet file and MSI within but the script is only trying to extract .cab files not .msi. The new version handles that.
The next thing is to extract the MSI, which can be done with lessmsi.

I've updated the script to handle that when using --include-old-versions. If you have already run the script you will need to delete vcruntime_8.0.50727.619501 for it to take affect.
