I.m sorry but it's not working.
I use MC17, never used an older version.
I used IE to go to
https://rover.jriver.com/cgi-bin/restore.cgi and entered my Registration Code and clicked on Restore.
It did it's thing and gave me my registration code link (the code is the same as the one I entered).
It said it should have been installed automatically. It didn't.
I clicked on the link and still get the error=22.
I am not sure how you want me to cut and paste. I don't see where to paste in MC17.
The emails I get also give the same error=22.
