Dolby Home Theater V4 is not working on my computer after upgrading to Windows10.

Clicking Dolby Icon at Control Panel will give message "Cannot find .startup file!"

Hi @jodpar2002,

Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community!

I came across your post about the Notebook, and wanted to assist you! I have looked into your issue about your HP Pavilion dv6 Notebook and issues with Dolby Home Theater V4 not working correctly. You could  try using the Windows Update Troubleshooting tool to fix any updates that have not come through for Windows.  Please restart the Notebook twice to make sure all update have been completed!

I would be happy to assist if needed as there are many models of HP Pavilion dv6 Notebooks, I would need the model number.
How Do I Find My Model Number or Product Number?

Please let me know how this goes.

Hey @jodpar2002,

First, try to click the Windows icon, type services in the Search box, and then click or tap View Local Services. Scroll down to the Windows Installer. Startup type should be - Automatic, and Service Status should be - started
Restart the computer after this step and try installing again.

Thanks.

Windows Installer. Startup type is always -Manual. Service Status is -Stopped.

I tried to Start the service and install, same result.

Hey @jodpar2002,

You will have to reinstall Windows 10 on this Notebook. Something in the registry  is corrupt or having an issue. The Windows installer is off and needs to be on Automatic and Started to work.  Here is a link from Microsoft on performing a Clean installation of Windows 10.

Please let me know how this goes.

Thanks.

After clean installation of Win 10, Dolby Home Theater V4 icon is gone.

Hey @jodpar2002,

Try updating the IDT High-Definition (HD) Audio Driver and Software.

Before you updated did you check to see if the system would update all software and drivers?

You could  try using the Windows Update Troubleshooting tool to fix any updates that have not come through for Windows.  Please restart the Notebook twice to make sure all update have been completed!

Thanks.

IDT High-Definition (HD) Audio Driver and Software are gone also.

Hey @jodpar2002,

You could try sp55094.exe. There are no drivers created for Windows 10 and this system.

Thanks.
