Trouble Installing Craft 2.5 on Windows 10 Using Wamp 2.5 I am trying to install Craft CMS 2.5 on a Windows 10 machine using WAMP 2.5.

I just downloaded both Craft and WAMP this morning — so both are fresh installs.

I believe I have done everything properly, but when I navigate to localhost/sitename/public I get the following message:


  Service Unavailable
  
  Our site is temporarily unavailable. Please try again later.


If I try navigating to localhost/sitename/public/admin OR localhost/sitename/admin I get the following message:


  Not Found
  
  The requested URL /sitename/admin was not found on this server.
  
  Apache/2.4.9 (Win64) PHP/5.5.12 Server at localhost Port 80


These are the steps I took when setting up:


Created a folder in wamp/www called sitename
Copied the craft and public folders into the sitename folder
Changed htaccess to .htaccess (using windows command line)
Created database in phpmyadmin
Updated db.php in craft/config folder


(the only change I had to make was to add the database name — I left server as localhost, user as root and password blank.  I did change the tablePrefix to five different letters — i.e., no numbers or special characters)

I did NOT change the permissions on any of the app, config or storage folders for the simple reason that I do not know how to do that on Windows.  

Unless the permissions are the problem, then I do not know why I am having this problem.  

Any ideas?
Alec Ritson's comment solved the problem.  His advice was to try 

localhost/sitename/public/index.php/admin


In other words, I had to add index.php to the URL (after public but before admin) and then everything worked fine.
