Looking at the files, it looks like different servers. Look at the E: drive, it's a CD/DVD on one and an internal HD on the other. This is more than just an in place upgrade.
It looks like you have a few leftover files from the "upgrade". The URL has actually changed in 7.7.2 to /ConfigurationCenter (no "ServiceDesk." and "-er" instead of "-re") so try that instead.
Ah yes! So it has..
It did mention:
"If you have configured Service Desk console in this way, you will need to update the Configuration
Center URL to the new location using the Touchpaper.Tools.AppConfigUpdate.exe tool."
in the upgrade doc but didn't say anything else. I should have paid closer attention. That in the section for "selecting the framework instance in console" though.
Might be worth specifying that somewhere in the docs or here LANDesk Service Desk 7.7 Release Information and Useful Links
The file locations were from 2 different installations, I was just using it as an example of the differences in file structure for the same location in the 2 different versions of Service Desk
