You can install on as many machines as you like. Of all those machines you can only have two signed in for use. Of those two machines you can only be using the subscription on one at a time.
A single user license cannot be shared. You will need to acquire a license for teams if you wish to have more than one person using the software.
So you have to pay 10$ more to get a company license?!
Because a individual license is 60$ and a company license is 70$.
but i can't find the number of devices anywhere?
how many machines can run at the same time with a company license?!
It depends on how many machines you want to have licensed when you have a company license. I believe the $70 is for each machine. It is cheaper to not get team licenses.
