Good day !
Dotnetnuke installer installed everything worked.
Then he had to move it to another location.
As if everything is working , the starting page is loaded .
But here in the transition , an internal page , I get a 404 error .

Error description:
Error HTTP 404.0 - Not Found
To find a resource has been removed, had its name changed , or is temporarily unavailable .

What to do?
I did not change the directory . Paths are the same.
Most have changed the settings in IIS 7. The ones I know about , it is necessary to configure virtual directories , something like mod_rewrite, as in Apache .
But something will not understand how to do it .
I understand that it is something with the settings , but what exactly is not clear.
Somehow finding the problem is not solved .

Thank you.
