Vertex O Series Upgrade
All instances of Vertex O Series should be upgraded to the current version – Vertex O Series 9.0. Versions prior to 9.0 rely on Adobe Flash Player. Use of Adobe Flash poses a security risk to your network and data. O Series 9.0 is using HTML5 for improved security and performance. MKS Tax performs expedited upgrades to Vertex O Series 9.0 via remote access or on-site.
