Cause

The issue is due to the Windows option "driver signature enforcement" which is enabled by default and is more strict when it comes to tracking and verification of device drivers attempted to be installed on a given Windows system.

Resolution

Temporarily disabling the driver signature verification addresses this issue. Disable the signature verification on the host with command bcdedit /set testsigning on Reboot the host.Install PowerPathReenable the signature verification feature on the host with command bcdedit /set testsigning off Reboot the host.
