Sapphire v6 AVX2 should not be installed at the same time as Sapphire v2 or v3 AVX2. The v6 installer should replace the v2/v3 AVX2 version, and sequences saved with v2/v3 AVX2 should automatically be promoted to v6.

Sapphire v2/v3 and v6 plug-ins are split into multiple "Sapphire2" and "Sapphire3" categories.

If you intend on using an older Avid DS product that did not support AVX2, be sure to use the AVX1 version, which is indicated with an "(avx1)" appended to the category name.
