The activation key is a 32 characters key used to identify your license purchase. Keep it safely somewhere because you will need it when activating and synchronizing your license.
Please visitto buy a or an extension for the period. Then you will get the activation key from us by email.
You will get as many activation keys as licenses you purchased.
•: to enjoy full capabilities of PVsyst you have to activate it, this requires the activation key.
•: when you purchase an update support extension or when you have to freely renew your license, the license needs to be synchronized. This also requires the activation key but if the activation procedure was already done the activation key was stored in PVsyst, so you do not need to remember it.
•: if you have to switch your license to another computer, you will first deactivate it on the old computer and then activate it on the new one(this is a regular license activation, it therefore needs the activation key).
