Hello Sacha, if I buy the perpetual license and want to uninstall the program on one computer and put it on another, I spend 2 licenses so I have 3 licenses or how I uninstalled and installed on another computer I only used 1 license with 4 yet?
The simple answer is, you don't worry about it. :)
While uninstallation decreases a license count, but sometimes (may be because of non-availability of internet) it doesn't. If you have shortage of license because of this just let me know. I will increase it. :)
