I can't change the license

Is the license file that you want to rehost a purchased license or evaluation license?

If it is evaluation license, then you just need to generate a new evaluation license from the SSLC.

If it is a purchased license, check the Available Rehosts number # for the license rehost.

If the rehost number is 0, then you can not rehost the license.

If that the case, could you provide the screenshot of the license file you plan to rehost (LR-XXXXXXX) and the Available Rehosts number #?

I will send you a private email for further details.

Please checkout this user guide on how to rehost the license if the Available Rehosts number # is Not Zero.
