If Driver Updater gives an error that your license key is invalid, try the following:
- Make sure to copy and paste your license key during activation.
- License codes are specific to Driver Updater program versions. For example: a license code for version 7.x won’t work on version 9.x.
- If you change your PC or operating system, your old key won't work. Contact our support to get a new key in such situations.
Note: Driver Updater and PC Cleaner are two separate products. The license key for one won't work with the other.
