Adding & Removing License Keys
In a nutshell
Programmer keys (Developer, Engine, OEM) can only be installed into interpreted databases. These keys are physically written in the 4D structure file and stay there until they are removed. Interpreted structure files can safely be compiled — installed plug-in keys will still be there in the resulting compiled structure file.
End-User keys (Server Expansion, Runtime) should be installed into interpreted or compiled databases depending on their kind. These keys are physically written in the Escape folder, inside the 4D folder of the machine on which they are installed.
WARNING An error message saying that the kind of key is not applicable will be issued when attempting to install keys into a database that is not appropriate, e.g. programmer key into a compiled database.
Online activation of keys takes place when a key is first installed on a new machine. During activation, hardware identifiers of the machine are stored on Escape's activation server. User privacy is never put at risk in any stage of the activation procedure.
Offline activation is necessary if the computer is not allowed to access the internet; in such a case, pre-activated keys must be used. To obtain pre-activated keys for any specific machine, take note of the Machine ID and pass it to Escape when ordering your keys.
Demo mode is invoked when attempting to use the plug-in without a suitable license key. Demo mode will let the plug-in work for 30 minutes before restarting 4D.
The ELM (Escape License Manager) dialog
The ELM dialog lets review and modify all installed license keys of all Escape plug-ins, as well as obtain the computer's Machine ID (needed when ordering pre-activated license keys).
The ELM can be perused in both single-user and client/server.
To invoke the ELM dialog:
• In single-user: keep down CapsLock and Shift when launching the database.
• In client/server: choose Escape Licenses in 4D Server's Help menu.
Adding a key in single-user
There are two (ultimately converging) ways for doing this:
Start using the database and wait for the plug-in to prompt you asking for a suitable key:
Click Demo if you don't have a license key, to use the plug-in in Demo mode. If you have a license key, click Install key to launch the wizard and install it. Accept the License Agreement, and proceed as follows:
Invoke the ELM and click the Add button on the Catalog page.
No matter which method you will choose, the procedure steps are the following:
|Step 1||Carefully copy all lines of the license key from your delivery email and paste it into the entry area.
When done, click Next to decode and validate the key.
|Step 2||The key has been decoded and validated, and its details are now displayed. Make sure you are installing the right one.
If this is not the right key, click Back to correct the mistake.
Click Next to activate and install the key (an internet connection is required for activation).
|Step 3||The license key has been installed and you are seeing the Catalog tab of the dialog.
To install another key, click Add.
When done, click Done to close the dialog.
Obtaining pre-activated license keys
The third tab of the ELM window shows the Machine ID of the computer. This is a hardware-based identifier for creating license keys that work only on this specific machine.
Such keys are pre-activated, i.e. they do not require online activation, so they can be used on computers that are not allowed to access the internet.
Take note of your machine's Machine ID and send it to Escape when ordering pre-activated keys for this machine.
Adding & removing keys in client/server
In client/server the administration of license keys is done exclusively from the ELM dialog, which can be invoked from the 4D Server's Help menu, item Escape Licenses.
To start adding a key, click the Add button in the Catalog page of the dialog.
Where is licensing information stored?
Programmer keys (Developer, Engine, OEM) are stored in the structure file. The keys remain unaltered as the structure undergoes compilation, merging with 4D Volume, renaming, or even compacting.
End-user keys (Runtime, Server Expansion) are stored in a .QLC file that resides in the Escape folder inside the 4D folder of the machine (in c/s this refers to the server machine). The name of the .QLC file is based on the name of the database (using only the letters, not the numbers or other characters).
