Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Generally if you remove it from the old system you can install it on another system. However some companies which preinstall software sometimes lock the software to their system or they don't provide a way of reinstalling.
I personally would make sure the software installs and works before removing it from the old system. It's common sense, but may be against the EULA.
Generally you can copy the third party software and install it on another machine. In practice it usually installs and runs. You will have to check your EULA on your individual copy installed on your Dell to see if it is legal.
