Install Options

All of the fields on this panel are optional. You can customize your installer so it displays a license or readme file. And, you can assign the directory name where you'd like to suggest your customer install your application. Plus, if you only want authorized users to be able to install your application, then you can password protect your installer. If you'd like to customize your installer, then use the Custom panel and if you want to customize your updater, then use the .

License filename

If you want the user to agree to your license before installing, then enter the filename for your license html filename or click the Browse button. If you do not want to require a license as part of the installation, then leave this field blank.

We strongly recommend that you not use a generic name, such as license.html, but instead name the file something unique, such as [ApplicationName]License.html. Also, the filename should end in .html or .htm if you'd like the best formatting.

You can distribute separate license files for each international language that JExpress supports. Simply create an html file with the English version of the license in the filename you specify in this field, referred to as the base filename. Then create one html file for each other language that you want to distribute with the same base filename and the 2 letter extension matching the language. For example, if you name the base filename license.html, then you'd create the German version in a file called license.html.de and the French version in a file called license.html.fr. If you don't include a special file for a supported language, then JExpress simply displays the file specified in this field. All the international license files must be in the same directory as the base filename.

 


 

ReadMe filename

If you'd like your customers to view a ReadMe file during installation, then specify the filename, including the pathname, that contains the ReadMe html file or click the Browse button. Leave the field blank if you don't want a readme shown during the installation of your application.

We strongly recommend that you not use a generic name, such as readme.html, but instead name the file something unique, such as [ApplicationName]Readme.html. Also, the filename should end in .html or .htm if you'd like the best formatting.

You can distribute separate ReadMe files for each international language that JExpress supports. Simply create an html file with the English version of the ReadMe in the filename you specify in this field, referred to as the base file. Then create one html file for each other language that you want to distribute with the same base filename and the 2 letter extension matching the language. For example, if you name the ReadMe file readme.html, then you'd create the Spanish version in a file called readme.html.es and the Polish version in a file called readme.html.pl. If you don't include a special file for a supported language, then JExpress simply displays the base file. All the international ReadMe files must be in the same directory as the base filename.

 


 

Default install directory

Fill in the default installation directory for your application. We strongly recommend that you enter the default directory without a leading directory separator (e.g., / or \) because most users on a networked Windows or Unix system can't install into the root directory.

If the default directory name starts with a directory separator (i.e., / or \), then the default directory is created in the root. If you do not include a leading directory separator, then the default directory is adapted to the local environment.

For example, if you specified the default directory as MyCompany/Application (i.e., without the leading directory separator), then the default directory on a Windows machine would be \Program Files\MyCompany\Application and on a Unix machine /bin/MyCompany/Application. But, if you specified the default directory as /MyCompany/Application (i.e., with the leading directory separator), then the default directory would be \MyCompany\Application on a Windows machine and /MyCompany/Application on a Unix machine.

If you leave this field blank, then JExpress uses the name of the project (i.e., the .jex filename) to determine the name of the default installation directory on the target machine. It also uses the target machine's OS to determine the logical place to create the directory.

For example, if your project name is Test.jex and your customer installs your application on a Windows machine, then the default directory is "\Program files\Test". If the customer installs your app on a Unix system, then the default directory is Test under their home directory.

If you create a multiple component installer or a multiple target directory installer, then the default directory will be adjusted to include the name of the component or target directory. For example, You have the components Hello, Goodbye, and SeeYa defined. The user selects the Hello component. The default directory for Hello will include Hello as a subdirectory of the standard default directory.

 


 

Installation password

If you'd like your installer password protected, then simply enter the password into this field. JExpress encodes your password in the installer for security. The installer cannot be operated until the correct password is entered.
