How can I reinstall the dolby home theater?

I had sound problems with my Aspire V3 (571 G). I heard a noise dry while listening to music and watching videos. It was really boring. I thought it was a problem with the Dolby Home Theater v4, so I went to the control panel > uninstall a program > cinema dolby Home > repair. It does not solve the problem, so I went to C:\ and copied the 'Dolby PCEE4' folder, then I uninstalled the thought of Dolby Home Theater v4 that I will reinstall it by putting the folder to the directory. While it has been uninstalled, I discovered that the problem was not the home Dolby cinema, instead, it was a kind of audio enhancement, so I disabled it by clicking on Audio > manage audio devices > Speakers > properties > improvements and I ticked the box: "turn off all sound effects. The sound is fine, it does not sound dry but now I can't reinstall Dolby Home Theater v4. I put the 'Dolby PCEE4' folder to the C:\ directory and it did not work. I opened the case and found a command called 'install' so I ran the command, but it created only 15000 + (3,79 GB) files in the folder and the home theater Dolby has not yet been installed. So I went to http://us.acer.com/ac/en/US/content/drivers and I entered my name of the model and the OS (Windows 8), but it wasn't a "Home Cinema Dolby' application or a driver available for download. How can I reinstall the Dolby Home Theater v4?

Think, it comes with the realtek drivers, cause after the failure of windows 8 and install the drivers for it on windows 7, it was the home theater dolby. And the realtek drivers

    You have a hard drive partition to do - but you would need to contact/see the FAQ from the hardware manufacturer (HP, Dell, Gateway, Lenovo, etc) to see if and how.

    Otherwise - you might have to order (pay for possibly) the factory restore/recovery of the value of the manufacturer.

  • How can I reinstall the RTL 120 BPL file?

    Original title: rtl 120 bpl

    How can I reinstall the RTL 120 BPL file

    Rtl120.bpl file has Nothing to do with Microsoft Windows.

    It's just a B orland Precompiled Llibrary file with a third party software provider.

    File rtl120.bpl Embarcadero Technologies and is installed on your system to third party such as software packages:

    AVG (their component PC Analyzer)
    TuneUp Utilities
    Advanced System Care (ASC)
    IOBit Malware Fighter Pro

    For example, if you have installed Advanced System Care and rtl120.bpl file that is installed with it goes missing, the message may look like this:

    ASC.exe - Unable to locate component
    This application has failed to start because rtl120.bpl not found.  Reinstalling the application may fix this problem.

    There may be other third-party applications that installs the file, but if you do not provide the exact error message in its entirety person aren't going to be able to help.  And given that the file has absolutely nothing to do with Microsoft Windows, maybe nobody in the Microsoft community will be able to help you without more complete information - like the error message and that if one of these third-party applications (or those like him) you have installed.

    If the system has worked very well and now the file seems to be missing for some reason, it was probably quarantined (effectively deleted) your antivirus/antimalware unspecified software applications.  Perhaps you can also find an updated file in quarantine and he unquarantine.

    With too little information provided, you can expect only theories and speculation about what the problem is and how to fix it.

    If you have one of these types of third party applications or where the product description includes descriptive as sentences:

    cleaner, mechanic, stop at the stand, detective, doctor, heal, optimize, Inspector, clean, tune up, speed up, fix up, compact, compress, faster, power, boost, boost, gum, muncher. Click fix, instant fix, new, intuitive, errors, stops freezes, stops crashing, stop crashes, stops errors, improves, saving you money, risk free, guaranteed or any third-party program that has an icon that looks like a gear, pinion, belt holders, key, key, screwdriver or plunging arrows?

    You may need to uninstall and reinstall these applications (do what the error message).

    If you have this error and none of these products have been installed and reinstall does not help, then you must go to the support page help because the file has nothing to do with Microsoft Windows.

    You might be able to solve the problem to simply uninstall and then reinstall the distressed product (do says what that error message).

    How did you accidentally remove it and isn't in the trash for restore you?

    It seems that this file belongs to The Embassy Suite from Wave Systems Corp. and is shipped on some Dell computers.  It is not an XP file and has nothing to do with XP.  What a pity that it knows absolutely nothing about your system (thanks, MS Answers).

    I seriously doubt that the restoration of the system will help you, because this file has nothing to do with XP.  That looks like an engineer of 'expert' technical support which is retained by Microsoft wild goose chase.   Anything for a reply with a link to a KB article...

    I do not have this software, but it seems that you might be able to download and reinstall from the site WWW Dell here.

    If you are not sure and that the download is not look right, you could post a message in the forums of Dell support or wave of support.
