  • Why does the software say my serial number is invalid?

This means there is something wrong with what you have entered and the software does not recognize it.  Please make sure to copy exactly from your order confirmation email.

Usually, the most common mistakes that cause this error are:

– Entering something other than the serial number, like an order number or SKU.  Your serial should be in this format:

  • MacDrive Pro: MX###-#####-#####-#####
  • MacDrive Standard: MD###-#####-#####-#####
  • MacDrive 8: MD8-#########-#####-###
  • Disk Aware: DA1EW-R????-?????-?????

– Having a different version installed than you purchased, most commonly trying to activate MacDrive Standard instead of Pro or vice versa, or trying to use a MacDrive 8 serial with MacDrive 10.

– Having extra or missing characters in the serial number, or other typos.
