Hi,
Unfortunately Windows Installer does not generate an unique ID for each installation. However, this can be done through a
custom action. This custom action can be scheduled before the information is sent to your server and it can set a custom property to the unique string. The property can then be added to
HttpPostCollectData in order to send it to the server.
Please note that your script on the server should also be modified in order to receive the unique string.
Regards,
Cosmin
