This is interesting. I now have BUMP7.1 on my system . But there is more to the story.
I downloaded the file you mention from the EMC9 Home. That would not install, as it kept finding an older version of BUMP on my system, and kept trying to uninstall it (unsuccessfully). I exited that process after a few attempts.
However, it gave me an idea: I have had BUMP on my system from previous installations of EMC7, 8 and possibly even Backup Exec when it was owned by Quest Software. I guessed that EMC9 installer did not uninstall BUMP 6 properly, and all subsequent attempts by it (and the updater you suggested) was choking on the remains of that previous BUMP.
So, I deleted all instances of "BUMP_" and "sbewin32" from the registry. Now the updater installed and I have Roxio Backup AND Backup MyPC 7 on my computer (and they still look very different :-) )
However, BUMP was installed to "C:\Program Files\Sonic\Backup MyPC Deluxe 7" location and has it's own group under the Start menu.
I bet this will confuse the installer/updater for EMC 10 when I upgrade to that in due course!!
Anyway, thanks to all who participated in this thread. Problem is solved.
