Multi-Computer licensing will allow a user to install and use the software on more than one computer
using the same License Activation Code (up to 3 computers). A typical use of Single-User / Multi-Computer Licensing is
when you would like to allow
a user to install the software on both a desktop computer and a laptop computer.
The Multi-Computer feature will keep track of the anonymous
<machineID> of each computer. Re-activations will count against the re-activation lockout
and against the Multi-Computer counter.
There are two important options to consider for Multi-Computer licenses:
- Roll-Over Re-activation
- User Authentication
To enable or disable Roll-Over Re-activation for a Product, view the Product Configuration and
edit () the License Settings for this product.
Advantages of each scenario are detailed below.
NOTE: Once the product is ACTIVE,
you will not be able to change this option. Perform all your testing
under TESTING MODE
With Roll-Over Re-activation
Re-activation of a License is typically required when a User is replacing one of his computers and now wants
to install your application on his new computer. If this new installation is within the limits that you have set
on the maximum number of computers for this License (i.e. 1,2 or 3), then the re-activation will be allowed.
If this new installation would exceed the maximum number of computers allowed, then
Roll-Over Re-activation will allow this new computer to be activated and will
disable the previously activated computers to keep the number of computers within the maximum limit.
With Roll-Over Re-activation:
The User can re-activate on a new computer exceeding the maximum number of computers
without your intervention
Previously activated computers will be disabled automaticatlly.
The user does not need to first explicitely de-activate a computer/device, providing a less complex
User experience (a consideration
if the previous computer was damaged, lost or stolen).
The User will need to provide a "New and Never Used Password".
The number of re-activations allowed is controlled by the Re-Activation Lockout settings of the DNA Product.
Without Roll-Over Re-activation
When the User attempts to install on a new computer that would exceed the maximum number
of computers allowed by the License, the re-activation will be rejected. The User must first de-activate
one of the previously activated computers before he can proceed to a new installation.
A key difference is that the User will not be asked for a "New and Never Used Password". The License Password
will remain the same unless changed by the User via the License Portal / Manager.
Without Roll-Over Re-activation:
The User cannot re-activate on a new computer exceeding the maximum number of computers
of the License.
The User must explicitely de-activate a previously activated computer before re-activating on the
The User may need your intervention if he has forgotten to de-activate the previous computer
(a consideration if the previous computer was damaged, lost or stolen).
The User does not need to change his License Password.
The number of re-activations allowed is controlled by the Re-Activation Lockout settings of the
User Authentication - Use of a License Code Password - highly recommended
User Authentication adds a License Code Password (max 16 characters) associated with the
License Activation Code and is unique to software_DNA. The License Code Password is a second level
of security and authentication that provides several benefits to your Users while reducing your Technical Support efforts:
Users can self-reinstall their software application on a new computer / device without the need to de-activate on the
previous computer, and without your intervention, within some reasonable configurable limits (the Re-activation
The User's License is more secure, requiring the License Code Password to install and re-install the
The User has access to the License Manager that allows them to manage their License Code, including
retrieving their password, changing their email address associated with the License, etc.
One part of any secure Licensing system like software_DNA is locking the License to a specific computer. The
challenge comes when
the legitimate user changes / loses / damages his computer
and now needs to re-install the application on a new computer and more often than not, has not or was not able to
de-activate the application on the previous computer. With software_DNA and the use of a License Code Password,
the user can
himself securely re-install the application on a new computer, while still protecting you from piracy of your
Disabling User Authentication and the License Code Password
In some situations and for some applications, you may want to disable User Authentication and the need for a
License Code Password knowing
the software application is still "locked" to a computer. Before a User can re-install the application on a new computer,
the User must remember to De-Activate the License on the current computer, or request your assistance to reset the
License from the DNA Control Panel.
Most of the software_DNA Licensing features and options
are fully supported when User Authentication is disabled, but with the following constraints:
Multi-User ("x"-seat) licensing is not supported
The "Do-ALL" Windows API Call is not supported
Users do not have access to the License Manager to manage their License, although they can still retrieve the
list of Licenses associated with their email address, in case they have forgotten or lost their License
Users do not have access to the public Offline Activation portal, although you can continue to perform
Offline Activations on behalf of your users from the DNA Control Panel.
some coding changes for the software_DNA API calls are required in your application
Once the Product is ACTIVE, this setting can not be changed

Multi-Computer versus Multi-User Licensing
Multi-Computer is intended for use by one(1) License owner who would like to install the software
on multiple computers, such as his Desktop and his Laptop
Multi-User Licensing is intended for use by multiple users of one organization who share the License Activation
Code. You can have 10's, 100's and 1000's of seats per Multi-user License whereas Permitted Activations
will only allow 1, 2 or 3 computers
You can not mix Multi-Computer and Multi-User Licenses within the same DNA Product.
