* Extended Support
Add-On Products offers Extended support to clients using certain “Out of Mainstream Support” Microsoft products with our software. This allows you to retain support access for your Add-On Products software while continuing to use older Microsoft products.

Whenever Add-On Products releases a new ‘major release’ (like version 7.0 > version 7.1 or version 7.1 > version 8.0), we will update our system requirements for the product to only contain Microsoft platform products versions, which are in Microsoft Mainstream support. See Microsoft Lifecycle Policy.

If you use a Microsoft product which has ended its mainstream support, you may still be able to be covered by our support – just purchase extended support for the Add-On Products product in question. For more information, please contact your reseller or us directly by sending an email by clicking here.
