7-Zip 9.22 beta 64 bit and others

[zahnartz62]

Patch instructions by senior member said DL 7-zip to open rar for latest patch. Google to several options all seem to be by Igor Pavel. I have DL for almost 24 hours..screen shows rotating green bar and "soft32". I have gone to panel to uninstall..there are no instructions, clicking "change" is no help. It does not offer any instructions or directions..just an open window with icon. I have not DL anything like this..BTW I am 75 so please explain problem or solution in easy terms. Is there an easier way to open rar in order to patch CoD? Many thanks in advance. John
