Known Issues

The following issues might occur in this version of VMware Workstation Player.

  • Upgrading the guest to Windows 10 version 1511 might prevent VMware Tools related features from working
    When you upgrade major Windows versions, such as Windows 7, Windows 8, and Windows 8.1, to Windows 10 version 1511, VMware Tools related features, such as shared folders and Unity mode or view, do not work.
    Workaround: The following workarounds consist of the same steps, but performed at different points in relationship to the upgrade.
    • To prevent this issue from occurring, perform the following steps.
      1. Uninstall VMware Tools before you upgrade a Windows guest to Windows 10 version 1511.
      2. Reboot the virtual machine.
      3. After the upgrade, install VMware Tools again.
    • If this issue occurs after you upgrade to Windows 10 version 1511, perform the following steps to enable all VMware Tools related features to function.
      1. Uninstall VMware Tools from the guest operating system.
      2. Reboot the virtual machine.
      3. Reinstall VMware Tools.
  • The Easy Install option does not complete the installation for Windows 10 Version 1511 guests
    When you use the Easy Install option to install the Windows 10 version 1511 guest operating system, the installation process stops
    at the "Select the operating system you want to install” screen.
    Workaround: Complete the installation process manually by selecting an operating system and clicking Next.
  • On a Windows Server 2016 Technical Preview host, Help links do not appear
    When you attempt to access Help in VMware Workstation Pro or VMware Workstation Player on a Windows Server Technical Preview host, Microsoft Edge (the default browser) fails to launch, which prevents Help links from appearing. Instead, the following error message appears: The specified module cannot be found.
    Workaround: Change the default web browser from Microsoft Edge to a browser such as Internet Explorer, Chrome, or Firefox.

Resolved Issues

The following issues were resolved in this version of VMware Workstation Player.

  • During the Easy Install process, VMware Workstation Pro misinterprets Windows 10 Version 1511 ISO images as Windows server 2012 R2 images
    When creating a new virtual machine, if you select a Windows 10 version 1511 ISO file in the New Virtual Machine Wizard, the wizard says "Windows 10 detected. The operating system will use Easy Install". But in the next step, the "Version of Windows to install" dialog box only displays options for Windows Server 2012 R2.

    This issue is resolved.
  • The Microsoft Excel application responds to input with a one-second delay
    When you run Microsoft Excel 2013 on a Windows 10 virtual machine, the application responds to your input with a one-second delay.

    This issue is resolved.
  • A UAS device connected to a USB 3.0 port on a Windows 7 or later host might fail to successfully connect to the guest
    When a UAS device is connected to a guest operating system and you turn the device off and back on, the device does not successfully reconnect to the guest. In Workstation Pro when you select VM > Removable Devices, the device is listed as connected to the guest, but the device does not appear in Windows Explorer within the guest.

    This issue is resolved.
