I bought this to put on 3 computers. How do I do that. It keeps wanting me to buy on the other computer.
Hi debbiehouska and welcome to Avast! forums.
Follow the same procedure you did in the first compurer to the other 2 computers. Open the e-mail Avast! sent you and double-click the attached file License.avastlic in each of the other 2 computers. If you e-mail does not allow this procedure, you should download the License.avastlic file to the desktop and execute it from there.
