What is Source Guardian and why do I need it?

Source Guardian is a method of protection for php scripts. It helps us protect our software from piracy while being able to deliver the software at an affordable price. Some files within your software are encoded (encrypted) with Source Guardian encoding.
When php files are not encoded, they code can be read, changed, edited or copied and programmed to be run on any php enabled server. In order to stay competitive and to remain a leader in the proximity locator software industry, we must 'encode' or 'encrypt' our source code with Source Guardian in order to protect our rights as the original owner.
Since we choose to deliver our software with Source Guardian Encoding, it means that Source Guardian Loaders are required to be installed on your server to run Ultimate Locator v3. In most cases, it's not hard to get your server to have Source Guardian support.
Our Source Guardian encoded files require a few special files to be on your server. These files are called 'loaders' and simply need to be placed on your server in their own folder. Simply make sure you have a folder named /locator/ixed and it has the appropriate file for your server type. We include all the 'ixed loaders' you might need along with your software so you don't have to worry about finding and loading them.
Source Guardian files work with all versions of PHP.
Most operating systems and installations of PHP will load our encoded scripts without any modification. PHP will be able to find and load the appropriate loader if the following conditions are met:
1) Operating system and PHP mode:
Linux or FreeBSD - PHP installed as CGI or CLI
Linux or FreeBSD - PHP installed as Apache module (with thread safety off)
Windows - PHP installed as CGI or CLI
2) Thread Safety is disabled. You may check phpinfo() output for this.
3) dl() is enabled. You should have enable_dl=On in your php.ini.
4) The PHP extensions directory needs to exist. Please check that the extension_dir= option in php.ini points to the real directory. Some hosting companies have incorrect installations of PHP and this can cause problems.
5) The latest ixed loaders are installed in an /ixed/ subdirectory within your scripts directory or any parent directory. Examples are below:
6) (For windows users only) extension_dir= option in php.ini should point to the directory located *on the same drive* with your document root and scripts directory.
