Trying to install polycom viavideoii on windows 7 get message to install media player 7.1 or later then will not install, is there a way to get around this ?

The Sony NW LATER NWZ-A818 is a portable media player that was released in 2010. It may work with Windows 7 and 8, but it's officially supported only for Windows XP and Vista.
You can try to connect the device to a Windows 7 or 8 computer and see if it is recognized by the operating system, but if you run into any issues, it may be difficult to find troubleshooting solutions as the device is quite old.
It's always recommendable to check the device's official website or the manual to check the compatibility with the operating system you have.
It's also worth noting that newer versions of Windows may require additional drivers or software to be installed in order to recognize older devices like the NW NW LATER LATER NWZ-A818.

Use the latest firmware version in your MP3 device. If you have PC program to work with your Player, use windows media player instead

You don't need any driver if your PC has windows XP sp2 or later and Windows Media Player 11.
Try to do these steps:

1. Connect the player to the computer.
2. From the computer, select start - Control Panel - Performance and Maintenance - System. "System Properties" is displayed.
3. Select Hardware tab, and open Device manager.
4. Open Universal Serial Bus controllers, and select USB Mass Storage Device or WALKMAN NWZ-XXXXX.
5. Select Action - Update Driver ... from the menu bar. "Welcome to the Hardware Update Wizard" is displayed.
6. A dialog on Windows Update connection will be displayed. Select No, not this time., followed by Next.
7. Select Install from a list or specific location [Advanced], followed by Next for the hardware install method.
8. Select Don't search. I will choose the driver to install., followed by Next for the search and install option.
9. Check Show compatible hardware, and then select MTP Device* in the model list, followed by Next. The device driver is installed.
10. "Completing the Hardware Update Wizard" message is displayed, and confirm "MTP Device" message. Click Finish.

I hope this helps.
Good luck!
