• This release is based on Version 7.1/7.5 of the VDA Core Services for Windows Desktop (32-bit). It patches only systems where Version 7.1/7.5 of the VDA Core Services for Windows Desktop (32-bit) is installed.

New Fixes in This Release

1. This enhancement provides additional compatibility with Nvidia's GRID API related to GPU pass-through and vGPU use cases. Specifically, it addresses the following issues:

   • With GPU pass-through enabled, sessions with certain custom resolutions fail to launch.
   • In full-screen VDA sessions with a 2560x1600 custom resolution, switching among open applications and/or closing applications fails to refresh the session window. As a result, a ghost window remains on the screen.

Installing and Uninstalling this Release

Notes:

• Important: On Windows 7 devices, attempts to install this release on 7.1 or 7.5 VDAs that were upgraded from a 5.x VDA fail and the installation rolls back to the 7.1 or 7.5 state, respectively.. The issue occurs because the hotfix is trying to locate a file that is not present in 7.1 and 7.5 VDA installations that were upgraded from 5.x. As a workaround, run a Repair on the 7.1 or 7.5 VDA. Running a Repair restores the missing file to the proper location, allowing this hotfix to install successfully. To run a Repair on the 7.1 or 7.5 VDA, use the following command from the command line:
  msiexec /f {FF86AC66-0B68-4894-9746-8CCE16A16CD5}
  (Note: The x86 and x64 versions of the VDA have separate product codes).
