I downloaded SIM today (version 7.5.129) and also have the same error message when trying to install
Is there any news Symantec employees as to when we can get a working version?
I tried installing the previous one I had downloaded a few weeks ago (v7.5.92) and when I run it I get the error message saying it cant find the SQL Express install file from the remote server (error message "The remote server returned an error: (404) Not Found")
So now I am stuck, as I cant use the previous one nor the new one
Cheers
