Deactivate License for .NET Core Professional Edition

If you wish to deactivate NCache .NET Core, you can do so through Command Line or PowerShell tools.

Command Line Deactivation

To deactivate, you need to have the Deactivation Key from Alachisoft Sales.

For license deactivation, approach the /opt/ncache/bin/activation folder of NCache, where the activation script is placed. Here's the command for that:

cd opt/ncache/bin/activation

NCache is installed in the /opt/ncache folder by default.

sudo ./activate -d -k XXXXXXXXXXXX

-d indicates deactivation.

After running this command, you will be displayed with a confirmation message saying Your copy of NCache has been successfully deactivated.

Through Linux Command line, go to the directory where the activation script is placed

cd /opt/ncache/bin/activation

Execute the following command to generate the authorization code. This is specified with the -m parameter. The deactivation key (you got from Alachisoft) is provided with the -k parameter.

sudo ./activate -d -k XXXXXXXXXXXX -m

You will be prompted with a long encrypted text on the screen. This is the Deactivation Request Code.
Copy this to deactivate the license. You can do this two ways:

Method 1: Alachisoft Sales

Method 2: NCache Email Deactivation
