I've just updated my Z830 to Windows 10, and keep getting the following error message:

The current Dolby audio driver version 7.2.8000.17 and the software application expects driver version 7.2.7000.7.Please install a valid driver and software application combination.

The driver is looking for an earlier version, not the latest version, of the driver.

I've tried finding an answer to this problem but the only thing I've come across is an earlier thread on this forum about a
Z830-10U, with a suggestion to go to http://win10upgrade.toshiba.com/swup...=en&country=GB. Our model isn't listed, so the suggestion was to try the Z930. I tried this but it didn't work.

Could someone please advise on how I can fix this problem?
with thanks, Julieanne
