  • Hello,

    I tried to upgrade my acunetix from version 11.0.173271618 to the new version 12.0.180521161. Everything worked fine during installation, but then when I try to add a new target I get this message “Maximum number of allowed Targets reached.”. I have only one target configured and I’m trying to add the second one. Do you have an workaround for this issue?

    Thank you in advance.

    • Hi Dan,

      That is very strange. Here are some things to check / try:

      1. From the Acunetix UI, check the properties of your license from your Profile page.

      2. Can you try re-activating your license key using the Acunetix Activation application, which can be launched from the Acunetix program group?

  • Indeed the problem was caused by the failure to activate the license, although it returned the message that it was successfully activated.
    Thank you for your help.

  • We upgraded; now we get a message that the license needs renewal.
