Each license should apply to a specific PC - to the hardware on that PC, through the software on the PC, when you insert license key.
Would not have to be same location or same user, although the transaction for the 3 licenses will be to the one purchaser. ...
Noticed from your sig you're using avast! Pro which the above (at least for Pro 4.8.) is true.
The base AIS license is for three PCs. As I noted in my above post I have AIS. I received only one
license key that I used to install avast! on my three systems.
As I noted above was unable to find any info on the license details on either of the avast! sites. But per the language I posted above from avast! AIS Help it reads the license
(i.e., not licenses) is for multiple PCs "... use in your home
or on your small home/office network
."; i.e., a home user with multiple PCs.
If you can find language from avast! that supports what you posted, please post the link for it. Edit
Prior to AIS, I was using Pro 4.8 on one system, and Home on my other two systems. With Home 4.8 there was a discount on the upgrade for the AIS 3-PC license. But for the upgrade option for Pro 5.x version when I selected the 3 PCs option, the discount was only for one PC, not for the other two. The avast! 5 Pro upgrade cost for 3 PCs, 1-yr, was about $30 USD more than the AIS 5 3-PC license, 3-yrs. Hence the reason why I purchased AIS then did a custom install to not install firewall and spam filter.
