If you have already activated the software but then re-download and install the latest version of the software, only to find that the license key is invalid or cannot be used normally, it may be because the developer has changed the key algorithm or activation method. In fact, you don't need to worry too much. If the software is not updated, the key you have already applied for will usually not become invalid. If the key becomes invalid after upgrading to the latest installed software, you can simply use the machine code again to apply for a new key for activation.
What should I do if the key becomes invalid after updating the software?
