Hello is the activation permanent. What is happening if I need to reinstall startit11 or if I change computer.Do I need to buy a new key for reinstalled app or for app on new computer
Everything you will need is under your [downloads] in your dashboard.
you can always re download an installer later if you need to.
Also if you need to change your pc with the active install, under [downloads] at the end of your [key] there is a [...] if you click on that you can deactivate your current install and then switch to a new pc instead.
If you want more then one active install on multiple pc's then you will need to buy a new product key unless you bought the 5 pack which gives you 5 active installs on 5 different devices.
