How to Deactivate NCache License

Activated machines using the NCache license can be deactivated. By doing so, you can free up existing licenses, which can then be used to activate other machines.

Here are the steps that you need to go through to deactivate an NCache license.

Step 1

The first thing that you will need is a deactivation code. To receive a deactivation code you can send an email to This email should contain the existing license that you are using. Each license key needs a deactivation code which can be used to deactivate all the machines that have been activated using this key. The deactivation code will be sent by the Alachisoft Support team.

Step 2

Open the Activate NCache Tool, which is available at the following path:
Start -> All Programs -> NCache -> Activate NCache -> Activate NCache License
This will open the Activation Wizard. This tool needs to be run with Administrator Privileges.

Step 3

Select the option Deactivate NCache License and press Next.
