Below are the most common reasons why a serial number may not be working:
1. Serial number typed incorrectly or transposed. (Please check the serial number carefully and try again)
2. Serial number is being used with the wrong product or version of software. (For example: X5 serial numbers will NOT work with X6)
3. Coupon code used instead of serial number. If you have only a coupon code, please click here to obtain your serial numbers.
4. Nothing is entered into the User or Company Name field.
Note: If you have checked all of the above and your serial number is still not working, please Contact Support and include a screenshot of what you see when you enter your serial number into the correct Intego application you have purchased. To make a screenshot, press command+shift+3 (the '3' from the main keyboard, not the one of the numerical keypad). A screenshot will be saved to your Desktop.
