Fix #3

Uninstall Microsoft Visual C++ Redistributables Manually

When installing newer versions of the redistributable sometimes older versions have to be uninstalled, when this fails automatically as part of the install process, it can be as simple as doing it manually.

It’s important to remember you have carried out this step, as some programs may break when obscure versions of the Redistributable is uninstalled, it is usually reported and handled very well by programs and is as simple as reinstalling the prerequisite.

Fix #4

Delete Redistributables that you can't uninstall

Remnants can be left behind when uninstallations are interrupted, due to transient memory issues or the computer being shut down abruptly.

This step is only if you have issues or receive error messages while trying to uninstall any C++ redistributable

For this step, I suggest RevoUninstaller, it will allow you to delete any files associated with an uninstaller which may be corrupted and the programs associated Registry keys.
