I can't locate the drivers for that specific application, but something you can try is going into the eRecovery partition and choose the reinstall applications and drivers option. That should have all the drivers and applications that cam pre-installed on the unit. If you are trying to update, you can check the Acer Updater (if installed) and see if it will pull up the driver updates. Last thing is maybe checking Windows update for optional updates, they may be listed there.
Same here! I really have to "clean install" my Aspire V3-471G because still, if you upgrade, all prev. files will be placed in a Windows.old folder afterwards. So now, I have installed all the essential drivers as we had no backup of it, even this DOLBY which I really need. Acer guys, there's no Dolby driver on the available drivers we could download and install.
"Download the audio driver for the device and unzip it. The Dolby Home Theater v4 application installer can be found in a folder named "PCEE4" and the install executable is "DolbyHomeTheater.msi". Don't bother with "DolbyAdvancedAudio.msi" because it appears to just be a dumbed down version of DHTv4. Took me a while to find this out myself, hopefully you see this since your post was only a month ago."
