Summary0006069: Installer's certificate has invalid countersignature
DescriptionI have downloaded the most recent MassCert installer as of 2020-06-02, from (filesize: 3,589,016 bytes, sha256 aef9a60c27f04203ccd17fafbaf7f9323807a3776ab42db8c812da1ea6a5bf1c).

When I try to run this executable, Windows 10 shows the yellow UAC dialog "Do you want to allow this app from an unknown publisher to make changes to your device?", instead of the expected blue UAC dialog which shows the publisher to be KCSoftwares.

Viewing the exe properties and going to the Digital Signatures tab, then clicking Details, shows "One of the countersignatures is not valid. The file may have been altered."

I've attached some screenshots of the executable properties dialog and its various tabs. It appears that Windows thinks the signature is malformed, somehow.
TagsNo tags attached.

Fixed by re-generating and re-signing installers. Upload in progress.
FYI, we've checked all recent installers and KCleaner 3.7 was also affected.
