Windows 7 Driver Installs Successfully but App gives "Failed to load driver. Maybe installation was unsuccessful Exiting" error

[Vaniu]

In Windows 7, the driver installs successfully via PowerShell. But when I try to run the application, it says "Failed to load driver. Maybe installation was unsuccessful Exiting".

I fully understand the OS is no longer supported or updated. This is for a resource constrained device with no connection to the internet.
