Order of Operations

The license string is a software key that unlocks the full functionality of the component. Without the license string, Profiler Object will only function in demo mode.

You set the license string using an environment variable called MD_LICENSE. If you want to try out Profiler Object, see the section below about Demo Mode.

Alternatively, you can set the license with a call to the SetLicenseString function. Using an environment variable makes it much easier to update the license string without having to edit and re-compile the application.

Demo Mode

Profiler Object API has a Demo mode (no license is necessary) that will allow you to:

• Process up to 50k records per run.
• Result codes are all suppressed.
• The AppendMode is forced to be Overwrite only.

Windows

Windows users can set environment variables by doing the following:

1. Select Start > Settings, and then click Control Panel.
2. Double-click System, and then click the Advanced tab.
3. Click Environment Variables and then select either System Variables or Variables for the user X.
4. Click New.
5. Enter “MD_LICENSE” in the Variable Name box.
6. Enter the license string in the Variable Value box, and then click OK.

Please remember that these settings take effect only upon start of the program. It may be necessary to quit and restart the application to incorporate the changes.

Linux/Solaris/HP-UX/AIX

Unix-based OS users can simply set the license string via the following (use the actual license string, instead):

export MD_LICENSE=A1B2C3D4E5

If this setting is placed in the .profile, remember to restart the shell. The MD_LICENSE variable is shared across the entire Melissa Data product line of programming tools.
