# Overview

Here we provide instructions for the download and installation of PRIMER 7 (with PERMANOVA+). Please read this information in conjunction with our **End-User Licence Agreement** ([EULA](https://primere.5.deploy.net.nz/images/assets/fc38/1/eula_primer_version_7%20%281%29.pdf)).

These instructions are applicable to enable activation of single end-user licences of the software for any of the following sectors:
-	COMMERCIAL (Private enterprise, consultant, for-profit organisation)
-	PUBLIC (Government/State agency, museum, not-for-profit organisation)
-	ACADEMIC (University/College faculty, technicians and postdoctoral researchers)
-	STUDENT (Full-time student at undergraduate, Masters or PhD levels)

Your purchased **Licence Key** (32 characters) will authenticate the software. Your licence is identified by a unique **serial number**, which you should use in any communication with us regarding your licence.

#### Trial mode vs Fully-featured version
When PRIMER 7 (with PERMANOVA+) software was originally released, it could initially be run **in trial mode** (free for 30 days). However, as PRIMER 7 is no longer the most up-to-date version of our software (PRIMER 8 has now been released) you must already have purchased a valid PRIMER 7 licence key to install and run PRIMER 7 software. There is no longer any trial version available for PRIMER 7.

The full version of PRIMER 7 is activated by **entering your Licence Key** in the Install routine. A single end-user License Key for PRIMER 7 can be used to activate the fully-featured PRIMER software on up to two (2) computers (e.g., at home and at work).

If you need to move your PRIMER 7 software to a new machine (or re-image the machine), first **uninstall your Licence Key**. If you are unable to uninstall the Licence Key (e.g., due to machine failure), contact us on ***tech@primer-e.com***, and our technical team can **reset your Licence Key** for installation onto a new machine.

#### PRIMER 7 and the PERMANOVA+ add-on
If only the base package of PRIMER was purchased (without the PERMANOVA+ add-on), then the PERMANOVA+ routines will not be enabled and those menu items will not be visible. If you purchased PRIMER 7 with PERMANOVA+, your Licence Key will enable all routines.

If a single-user PERMANOVA+ licence, for use with PRIMER 6, was already registered to you then no further purchase of PERMANOVA+ would have been needed when you upgraded to PRIMER 7 – this add-on operates in essentially the same way with PRIMER 7 as it did with PRIMER 6. When you upgraded, you would have been given a single installation key, and your PRIMER 7 software would then include the PERMANOVA+ add-on as well, due to your pre-existing licence for this.

#### How do I know if I have the PERMANOVA+ add-on?
Once PRIMER is installed, click on **Help** > **About PRIMER...**. The splash screen will show the add-on as being present if you have purchased it (as in the image below). If your licence key includes PERMANOVA+, then you will also see the PERMANOVA+ menu item appear within PRIMER when you select a resemblance matrix in the workspace tree; almost all the routines in PERMANOVA+ begin from a chosen resemblance matrix.
