Need Quark 126.96.36.199 updater, link on this site doesn't work
I need the Updater to upgrade Quark 9.5.1 to Quark 188.8.131.52. 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!
