Activation

Set up the Proxifier

Config all traffic to Charles.
Open the Proxifier–>Advanced–>Advanced–>HTTP Proxy–>Enable HTTP proxy servers support

Proxy–>Add–>127.0.0.1:8888@HTTP

Modify HTTP Response

The Iris will be activated by communicate with the server, we can change the content of response to register it.
Open the Charles and Iris, and open the setting of Iris.
Fill any string in the field of license and click the Activate Code

And you can see the HTTP request in the Charles, the content of response will be NO_SUCH_CODE

The possible response:

• SUCCESS (This is what we need)

• NO_GIVEAWAY
• CODE_FOR_IRIS_MINI

We need to change the NO_SUCH_CODE to SUCCESS.
