* This program is used by the Vulkan Runtime Installer/Uninstaller to:

* - Copy the most recent version of vulkaninfo-<abimajor>-*.exe in
* C:\Windows\System32 to vulkaninfo.exe
* - The same thing is done for those files in C:\Windows\SysWOW64, but

* - Set the layer registry entried to point to the layer json files in
