No luck.

Here are the exact instructions per open-realty:
1. Extract the downloaded file(s) and upload to your website, either to the root folder on your site, usually called www or public html, or to a sub-folder of your root.
2. Using your web browser, go to
http://www.yourdomain.com/installpath/install/index.php. For example if you installed this on a domain called myrealestatecompany.com in a sub-directory called "open-realty" you would go to,
http://www.myrealestatecompany.com/o...tall/index.php.
Running the Installer
3. Read the license agreement and click the "Agree" button to continue.
4. Select the default language for your site and click submit.
My file manager shows me my path to your Web document root: /home/users/web/b376/pow.myrealestatecompany/htdocs
This is important, as most of your scripts will need to specify this location. For example, this is required if you'd like your PHP script to upload files.
I uploaded (FTP) the openrealty folder to: /htdocs
I can see the files in the /htdocs/openrealty folder in FTP and also my file manager but when I open a browser and type:
http://www.myrealestatecompany.com/h...tall/index.php
I get this: Not Found
The requested URL /home/users/web/b376/pow.myrealestatecompany/htdocs/openrealty/install/index.php was not found on this server.
Any thoughts?
I have tried:
http://www.myrealestatecompany.com/h...tall/index.php
http://www.myrealestatecompany.com/h...alty/index.php
http://www.myrealestatecompany.com/h...ocs/openrealty
Nothing seems to work.
