Installation Issues

Hello,
I've been trying to install open cart for the past 4 days but no luck..
I tried to install it manually following youtube instructions

the upload of zipped folder then unzipping
but it didn't work

then I tried to install it via application browser (go daddy)
I got the same error

I used another domain and tried to install via application browser
still getting the same error

can I know whats the problem?

the error am getting is

forbidden you don't have permission to access folder on this server
additionally, a 403 error was encountered, trying to use an error document to handle the request

forbidden you don't have permission to access folder on this server

Well, just place a simple image file into the Server ROOT(main) Directory, and
one image into the Server/ SHOP/ Directory. Then, call those images like:
http: // www. yourshopsite. com/yourimagename.jpg
http: // www. yourshopsite. com/yourshop/yourimagename.jpg
to first find out, if your Server is configured to be accessable, in the first Place.
