I sent an e-mail to avast, and have a free license key, but a can’t use him, because I can’t ''copy/paste" in to my avast reg form. my key is longer, from request code.
I assume you have registered on-line at avast.com and received an email from register @ avast.com (without the spaces) with the registration key, it should be fine, just ensure there is no trailing space after the registration key that you copy.
What errors are you getting ?
Q: “Invalid license number”. Why? http://www.avast.com/eng/faq-registration-license.html#idt_220 Or Insert Registration Key - Video
