In this case, it is very important to know which kind of license you own: a network license or a standalone one.A standalone license can be saved when the computer has ONLY been formatted (this means that no other component has been changed). The same is not applying for the network license – it will be lost.In the case of a standalone license with only a hard format performed, you only should activate the license again based on the serial number and the activation code, using the license management tool.
