The registration information you entered is invalid error

Even though I copied and pasted it from the incoming email, it says the login information is incorrect. I also ran the program as an administrator but could not find a solution.

For info could you tell us:

What Recuva version are you trying to register?
What version of Windows are you using?
Which AntiVirus are you using?

And just to be sure where did you purchase Recuva from, I assume it was the official website?

Common registration issues are:

Make sure that you are connected to the internet.

If typing in the key then be careful not to mistake letters and numbers. eg. 'S' and '5'. (I don't think Recuva keys use letters anyway)

If you are copy/pasting the key from the confirmation email then is there a leading space or trailing space after you have copied it over? If so then there shouldn't be.

Are you copy/pasting the name as well as the key? It needs to be exactly the same name that you used when purchasing.
PS. We have known people to make typos in their name when purchasing, so they then have to use the same typo when registering.

If you are still having problems then check if your AntiVirus is blocking the connection to Piriform/Avast servers?
Try disabling your AV before registering.

Try installing in Windows Safe Mode with networking.

Have you tried the other suggestions?

If you have and it's still not registering then you need to contact support to check your purchase and if there is something wrong with the key that you have been sent.
It's not something that we can do on the open forum. (For security/privacy we can't see licence information here).

You should email them at: support@ccleaner.com

If possible send your request from the same email address that you used when registering CCleaner.
(If that's not possible then noting that registered email address in your request, if you can, will make it easier for them to find your account).

You should get an automatic acknowledgement by return email that your request has been received and is in a queue for action, if you can't see one then check your email spam folder.
