PRIMER 6 Update

If you have installed the PERMANOVA+ add-on (additional product) then go here instead PERMANOVA+ update...

The current version of PRIMER is 6.1.18.

Note that this version uses the .Net Framework 4 and some older versions of Windows are no longer supported. It needs Windows XP with service pack 2 or later, Vista, 7, 8, 8.1, or 10. Either 32 bit or 64 bit is supported. If updating PRIMER versions before 6.1.13 this update includes some significant changes to program functions, and there is a manual supplement that can be downloaded below.

The update is applied as a patch and requires an undamaged PRIMER 6 installation.
