Dolby DIGItal HOME THEATER cannot be installed after upgrading to Windows 8.1

Hi there,
today i was forced by microsoft to upgrade from windows 8 to windows 8.1 I have problem with installing Dolby Digitial Theater Home app. I unistalled previous conexant drivers (windows 8) and installed new conexant (for windows8.1). I removed dolby. Then i went to C/Drivers/WIN/Audio/DolbyGUI/ there is setup.exe, dolbydigitalplusAA.msi and dolbydigitalplusHT.msi. THe setup.exe doesnt start installation, plusHT(home theater) gives message saying - cannot installed due to an error. However I can install dolby digital advanced audio, but I want my Home Theater back!!!! Can you please help me resolve this matter.... thank you
I have lenovo edge E531 with 8gb ram, intel core i5-3230M 2.6GHz, GeForce 740M

hi sotim01,
Thanks for posting!
1. Uninstall all components,
        Open Device Manager and Uninstall your Conexant audio under Sound and ganing controllers (make sure to place a check under delete driver software for this device)
2. Open Control Panel Uninstall a program and highlight the dolby component and an Uninstall button will appear.
3. Open your C: drive and Delete any folder that says drivers if non then continue with the next step
4. Download this Driver for installation
        Conexant Audio Driver  
Install it and continue
5. Open Drive C: now and you should have the Drivers folder back.
      Open that, Open Connexant Open Dolby Gui,  then you should have Dolbyaa for Advanced audio.
Restart your PC and there you go!
Let me know your findings
Cheers!

  • Dolby Home Theater v4 not working after upgrading to Windows 10

    Hi there, I just upgraded to Wndows 10 Home from Windows 8.1; everything went smoothly except for the fact that Dolby Home Theater v4 does not work. I had to reinstall it using the .msi file found in the Realtek Audi folders. I chose v4 over any of the other versions because I like how I can tune the equalizer to my liking and different uses. Anyways, the regular audio works and Dolby is turned on but there is no activity appearing on the equalizer and my music does not change once adjusted. Had this problem when doing an optional audio driver update in the past when I was running 8.1. I do not have the option to rollback the driver after upgrading to Windows 10. Does anyone have a solution to this issue or know what the correct Realtek driver is to make Dolby work? This is one of my favorite features of my laptop and I really want it up and running again! Thank you in advance! JakeStiebs My unit: Lenovo Ideapad Z580 running Windows 10 Home with Realtek Audio Driver 6.0.1.7535

    one more thing. I was not able to download cleanup tool/online scanner too. but may be it has something to do with my internet bandwidth. and other strange thing i observed is that before restart i was not even able to turn off all security features. but after restart that problem seems to be corrected.

  • No audio device installed after upgrading to windows 7???

    after upgrading to windows 7 audio is not working error audio device not install driver error...

    Hi,
    You will need to identify your CPU and chipset. CPU-z is a free and safe utility that can do that for you.
      If your system has an Intel chipset with disccrete or onboard graphics or an NVIDIA chipset with onboard graphics, then the drivers are here at this Realtek download page.
    If your notebook is an AMD CPU and NVIDIA chipset, with a discrete graphics module installed, then the driver for your Conexant CX20549-12 will be here.
    Post you results here in your thread so others rsearching for the same information can benefit from it. 
    Best regards,

  • Driver for Officejet 4500 Wireless all-in-one will not install after upgrading to Windows 8.1

    Upgraded to Windows 8.1 on Pavilion g6.  Officejet 4500 Wireless all-in-one still prints but won't scan.  Downloaded full feature driver.  Installation quit giving error message 'file cannot be found'.  Tried 'chat' sessions with no resolution

    Hello bob5e,
    I am sorry to hear that you are unable to install successfully on your Windows 8.1 with your Officejet 4500 Wireless. I can see that the installation quits on you, giving you an error message. I am going to recommend trying a couple of things to hopefully make the installation successful.
    1. First of all, try installing by using The Printer Install Wizard for Windows which finds the correct driver for your unit and installs it.
    2. If that does not work, please try this next troubleshooting document step by step.

  • HP Deskjet F2120 all in one printer driver not installing after upgrading to Windows 7

    I have a HP Deskjet F2120 all in one printer. I was working fine in Windows Vista Home Premium 32 bit.
    Once I upgraded to Windows 7 Home Premium 32 bit the driver is failing to install.
    I have tried all the solutions provided on the HP website but none of them worked.
    I also wrote a mail to HP support but they replied that its out of warranty hence they will not be able to help.
    If some genius can help me I will pray for him/her that all his/her wishes come true.
    Thanks you in advance.
    Imroz Baig

    I just got my HP Deskjet F2120 working in Windows 7.  Here's how:
    Insert the setup disk in your CD/DVD drive.  Choose to view the files in Explorer.  Scroll down to the file "Setup," which is identified as an application.
    Right-click the file and select "Properties." Click the "Compatibility" tab at the top of the resulting window.
    Check off "Run this program in compatability mode for:" and choose "Windows Vista" from the pop-up menu.
    ALSO check "Run this program as administrator" at the bottom of the window.
    Press "Apply," then "OK."
    Now you can double-click the "Setup" file and run the software installer.
    It will 100% work inshallah...

  • Vaio Care won't install after upgrade to Windows 10

    Upgraded to Windows 10. When the desktop came up Vaio Care was uninstalled and then reinstalled automatically. When I opened Vaio Care I noted I had a duplicate link for the program accelerator under the premium tools so I uninstalled Vaio Care and ran a registry cleaner and then downloaded Vaio care again from the software and driver page for my Windows 7 - VPCEB11GX. When I attempted to install got a message that it was the wrong software for my operating system and noted I need to install Vaio Care for Windows 8.1 64 bit. Can you please direct me to a download link for same? Thanks.

  • Reinstalled Adobe Acrobat XI Pro after upgrading to windows 8.1 and now cannot scan

    Reinstalled Adobe Acrobat XI Pro after upgrading to windows 8.1 and now cannot scan through Adobe, although Scanner says its combatible with Windows 8. Cannot reinstall drivers because Brother claims they're built-in. Help!

    1. Re: Reinstalled Adobe Acrobat XI Pro after upgrading to windows 8.1 and now cannot scan
    Anubha Goel
    I am using a Brother MFC 8460N and on Brother's site it says its compatible with win 8.1 and that the driver is already installed. When I try to scan I am told there is no preset (there was with win 7 though) and I have to "custom scan." When I try that, I hear a sound as if the printer is trying to scan, but the feeder can't pull the paper through. I then get a blank .pdf as my scan. Thanks for your advice. I will try that.

  • No Audio Output after Upgrading to windows 7; Soundblaster Card is installed

    After upgrading to Windows 7 Ultimate (64-bit), I found that my speakers (which are built into my HP w2207 monitor) are not recognized.  In the notification area I have the speaker with a red x in it, and it says “No Audio Output Device is installed”.
    I have a HP Pavilion D4890Y with the Sound Blaster Audigy X-FI 24-Bit Xtreme sound card.  I tried looking in Device Manager, and found “Multimedia Audio Controller” under Other, which states no drivers could be found.
    I tried following some of the advice online, and downloaded the latest Realtek High Definition Audio drivers, but and the download seems to run successfully, but I don’t notice any differences.  When I reboot as prompted, I’ve still got the same error.
    I then tried forcing the Audio Device to use a Realtek driver, but Windows protests (saying it’s not sure it’s compatable with my device, and I end up with “Realtek High Definition Audio” under “Sound, video and game controllers”, but it has a yellow exclamation point.  If I click properties, the device status says “This device cannot start (Code 10).” If I try to update the driver I get the message that it cannot find the driver software.   If I uninstall the driver I’m back to the original problem (multimedia audio controller under original devices, with no known drivers).
    I also tried downloading various files from the Creative site, but it’s not clear which one to use, and the 4 or 5 different ones I tried (including their recommended beta version for Windows 7), when each of them opens it says it can’t find any supported devices.
    Suggestions?  Thanks!

    Hi,
    "If the driver is a previous revision install it using the TROUBLESHOOT COMPATIBILITY tool that is part of the Windows 7 OS.
    To use the tool, uninstall any drivers for the sound card you show listed in Control Panel/Programs/Uninstall Programs  list.  Delete the Device from Device Manager. 
    Download the revision of the driver from www.creative.com  website to a folder you've created and placed on your desktop.
    After the driver is downloaded, navigate to the "setup.exe" of the driver and Right Click - select Troubleshoot Compatibility  ----
    Let the compatibility tool select a possible solution then use its suggestion of TRY RECOMMENDED WINDOWS SETTINGS, if it does not find a solution it will submit only CUSTOMIZE SETTINGS and let you install it as you designate."
    The preceding information comes from a Microsoft Windows 7 forum regarding an issue similar to yours.
    the information you provided did verify that it is a sound blaster XiFi Extreme card as checked against the Vendor / Device list.
    regards,
    erico

    I am having this same issue. I live in Korea and changing the language to Korean made the messages searchable, but when I changed back to  English, the problem returned and I was unable to search all my messages via the search window in the messages app, but then, after about 5 minutes, the messages app crashed, and after that, the problem was resolved. Gotta sat that I'm so far unimpressed with ios 8; seemingly not ready for Primetime.

  • HT2188 home button no longer working after upgrade to io6 on my iphone4...any ideas to fix this problem

    home button no longer working after upgrade to ios6 software on my iphone4..anything i can do to frix this or apple send me a new device.  phone no good without a home button

    The button's broken.  S**t happens.  Apple will replace your phone.  If in waranty it will be free of charge.  If not, you will pay $149. 
    You can elect to have it repaired at a 3rd party shop near you if you choose, but this will void all warranty if there's any left.

  • Cannot reinstate catalog after returning PC (Windows 7) to factory settings (because of worm infection). Catalog was backed up on external drive but not using PSE backup facility. Cannot find and *.tly file. Is this hopeless?

    Cannot reinstate catalog after returning PC (Windows 7) to factory settings (because of worm infection). Catalog was backed up on external drive but not using PSE backup facility. Cannot find and *.tly file. Is this hopeless?

    If you made backups of all of your photos and your catalog file using some third-party method (i.e. not using the PSE catalog backup command), then you should be able to restore everything.
    Step 1. Put the photos in the EXACT SAME LOCATION as before. For example, if they were in subfolders of C:\Users\<username>\Documents, then they must go into the exact same subfolders of C:\Users\<username>\Documents.
    Step 2. Move the catalog file to wherever you want it to be, and then double-click on it.
