When selecting Download from Services (manage subscriptions), Microsoft Edge reports that the signature of NSdownloader is corrupt or invalid. Looking at the executable, it says that the version is 5.1.0 and that the digital signature is sha1. We know that sha1 is being deprecated except that those with ancient browsers are not able to process newer sha signatures.
Is there reason to worry? Obviously, Microsoft Edge does not present a Run button after the install completes.
