DNA_DeActivate() API

DNA_DeActivate(Product_Key, Password)

Parameters Description
<Product_Key>

The <Product_Key> of your DNA Product.

The <Product_Key> is emailed to you when you create a Product in the DNA Control Panel and is available under Product Configuration in the DNA Product Control Panel.
<Password>

License Code Password, provided by:

  • If Product uses "User Authentication" option, then provided by the User
  • If Product does not use "User Authentication" option, then a hard-coded default Password used for all Licenses for this Product

For list of Error Codes and descriptions, see DNA Error Codes    .

The License Activation Code (retrieved from the CDM License File) for this <Product_Key> will be de-activated using the Password. This will free-up a "Computer" on a Single-User / Multi-Computer License, or free-up a "Seat" on a Multi-User or Floating License on the DNA Server.

The CDM License File will be disabled on the User’s computer.

If this is a Floating License, then a special "Floating CDM" will be created to allow for the re-activation of this computer on the next start-up.
See Floating Licenses     for more informaiton.
