New version hangs during installation

I decided to upgrade what has been an excellent program, as a mark of good faith, and now I cannot install version 7.02. The install goes OK until it reaches a previously-attempted account addition, gives a certificate warning, then presents a ‘Going Offline’ window and hangs.
Not very happy about this. Is there a fix, and can I also relocate my local folders when, or maybe if, we can get this sorted out?

Hello,
we cannot replicate this issue. Are you able to perhaps screenshot the certificate warning?

Regards,
Olivia
