There's probably a few different ways of resolving this, but I believe the issue is that you don't have administrative permission to save the file. 
 
-Browse to.. C:\Windows\System32  (or your equivalent) 
-Right click on notepad.exe 
-Select 'Run as Administrator' 
-In Notepad, File/Open.. browse to eqhost.txt, make your changes and try to save it with administrative privileges.
