Contribution is highly welcome. I'm poorly experienced with C#, so the current code is extremely clunky and works out of prayers. There's also far too many checks that I have no desire to optimize.
Following NuGet packages were used to create this app:
- Microsoft-WindowsAPICodePack-Shell by rpastric, contre, dahall - allows to create a Choose File dialogue box.
- RedistributableChecker by bitbeans - saves some effort checking for installed VC++ redist.
- And Microsoft's official packages such as System.Management for convenience and functional code.
