The full version of this software is linked to a single user and a single machine, with a licence that is unlimited in time. However, this is not a classic "RETAIL" licence; the key is generally associated with the PC's motherboard, which means that it is linked to this specific device and cannot be transferred to another computer. This licence is therefore considered to be an OEM or similar licence, which is non-transferable, unlike a Retail licence, which can be moved between several machines.
