Need Quark 18.104.22.168 updater, link on this site doesn't work
I need the Updater to upgrade Quark 9.5.1 to Quark 22.214.171.124. I downloaded the updater from the Quark.com site, but when I opened it I got an error message that the updater "could not be installed because the digital signature doesn't match and may be corrupt or tampered with."
Can anyone help me? Thank you!
