Where to Find Documentation

This document describes the issue(s) resolved by this release and includes installation instructions. For additional product information, including supported operating systems and system requirements, see XenApp and XenDesktop 7.6 on the Citrix Product Documentation site.

Known Issues in this Release

1. In rare cases, reinstalling this MSP file can cause the Citrix Display Driver (Citrix Systems – WDDM) to get marked for deletion. In turn, this causes the reinstall to fail, leaving the VDA’s display resolution unusable. As a workaround, restart the VDA and then reinstall the MSP. After restarting the VDA, the driver is removed. Then, when you reinstall the MSP, the drivers are successfully reinstalled.
