Presumably, you installed FH v7.0 over your existing FH v6.2.7 or some earlier FH version.

A ‘standalone’ GEDCOM file is, as it says in the message, not part of a Family Historian project.

Unfortunately, you did not include the top of the FH window that identifies the GEDCOM filename.

However, sometimes when installing new software such as a major upgrade to FH, your custom settings may get upset or reset to defaults.

That is why it is important to use the Backup and Restore Family Historian Settings plugin before such upgrades.

Nevertheless, you say the Project Window lists your previous Project.

So right-click that Project and choose Set as Default Project, which is what you would have done years ago in the previous FH version.

It will then have a green tick showing it will open by default the next time you open FH.

Finally, click the Open Project button.

That is even stranger and needs further investigation.

The filename is shown top left as ‘Untitled’ which probably means no file at all and the error messages are misleading.

Use Tools > Preferences… and open the Startup tab.

Please copy the entire contents of the Default Startup File: box into your next reply by using Ctrl+A, Ctrl+C and then Ctrl+V.

Is that file path the correct one for your project?

Please post a screenshot of the Project Window with the green tick and including all the buttons.

Confirm that clicking the Open Project button successfully opens that project.

Try using the More Tasks… button and select Samples > Reset Sample Project.

Does that successfully create a Family Historian Sample Project that you can open?

Presumably, you are running FH v7.0.8 from the same Windows PC Account Username as you ran FH v6.2.7.

Have there been any significant changes to your PC system between running FH v6.2.7 and running FH v7.0.8?

I have no idea how activation passwords and “info” has anything to do with the failures you reported, but glad that you solved it.
