After changing one or more options in the Product Activation Wizard of the License Management Tool (LMT) and then click the Finish button, user gets the following error:
Because of the error the change(s) made in the wizard will not be saved.
One of the values specified in the wizard (or the combination of them) is not valid. Or, as it has been observed, the LMT is in a state where no values can be saved from the frontend until one of them is changed.
Manually change one of the values in the registry.
