Issue Description

During the installation of the wireless adapter on Windows 7, some users might encounter the following error code 52 (Windows Cannot Verify the Digital Signature).
Due to this error, You won’t be able to install drivers for the wireless adapter.

Cause of the Problem

It is very likely that the computer does not have the necessary SHA-2 driver signature support. This was distributed through Windows updates, and users can review their installed updates to see if it's installed.SHA-2 driver signatures are required for all new hardware drivers produced after October 2014. SHA-2 driver signatures are native to Windows 8 and Windows 10, but not to Windows 7. Without the necessary update, Windows 7 will believe that a driver signed with SHA-2 is invalid, as it will not recognize the signature.
