Dolby Home Theater v4 setup error - another PCEE product installed

Hi,
when I try to install Dolby home theater it says-_" There is another PCEE product installed already. Please uninstall
it before installing this product. Setup will now exit"
any help will be very appreciated

Has any version been installed before in your system or now that you are installing?

yes i installed Dolby before and successfully using, i don't know what happened but suddenly those drivers are corrupted and gone from system tray icon and from programs and sound has been changed to "High definition Audio".
so now i am trying to install those again.

Few days back i installed Advanced System Care and cleaned my system, in that process i have deleted DriverStore folder as it popup with 12Gb space.

does this step caused in any way to corrupt my Dolby drivers?

Good morning! Recheck AI in the system otherwise have no files left of the previous installation, do a cleanup using the same Windows manager, type in the Run cleanmgr and select the drive for cleanup.
