KB4474419 introduces SHA-2 code sign support.Looks like this behavior is related to changes in drivers and updates signing of Microsoft products. Versions after 9.21.2 has only sha256 signing, and prior versions are signed with sha1.Īfter installing KB4474419 driver error 52 has been resolved, and TAP driver works fine. As mentioned at this forum thread last working version of tap-driver for clean Windows 7 install is 9.21.2, which has double signing: sha1 and sha256.
