license key not accepted

I just bought this CCleaner from Staples, it installs ok but it won't accept the key that came with it. What do I do now?

It would be better to get in touch with Piriform directly about this

I did not interpret the registration Key correctly. There is no number 1, if you see it, it means the letter I.

Sorry about this but it can be a good reminder for others. Thanks to the people for helping me.

Glad to hear you got it sorted Robert :)
