It is merely an update that you use for the older Patch versions. 7Before getting the PTE Patch, download and install the PTE Patch 6.0 followed by the PTE 6.1. However, the installation of the PTE Patch 7.1, 7.2, and 8.0 is optional. If you have already installed the PTE Patch 6.0 and 6.1, then move ahead with the installation guide of PTE Patch 8.1.
