Does this mean that I can only use Bandicam on one computer at a time?
If I may pop in, the
"If you purchase a 2-PC license, we will send one serial number which can be applied to 2 computers" means that if you purchased a 2-PC licence, it can be installed on two computers at the same time and used at the same time (since you essentially bought "two Bandicams").
The
"It's not a good idea because you have to share the same serial number" is a recommendation to not share the 2-PC licence with a friend at random, because if you ever lose that friend/become enemies or that friend is not careful with the Serial Number, they can possibly give it out to other people. This is not allowed with most purchased programs, and if it is detected that a large number of people are running the same Serial Number, it will be 'turned off' and not able to be used anymore (which could affect you, as you purchased the Serial Number). Thus, the advisory to not give it out to a friend, only keep Serial Numbers within the house/family. This is just a strong suggestion to protect yourself and the purchase you made.
At least, those are my interpretations of what Bandisoft meant. I hope that helps to make it clearer
