I have received no activation formula and am going rounfd in circles trying to find one. I just want to put my newly bought programme on a second computer
What avast version is this for avast Pro or avast Internet Security ?
Assuming that this is a multi user license ?
You can use the license file you got for the first computer, copy the license.avastlic file (you did save it ?) to the second computer.
You can install the program on the second system as you can use it for up to 30 days without having to enter the license file, so it gives you time to sort it out.
