How can I reinstall the cd/dvd player - Satellite P100 PSPAD

Hello

I have the Satellite P100 (PSPAD) and my cd/dvd drive (I do not know how or when) suddenly disappeard, it does not appear in my computer or Device Manager.
I tried this but coul not found the lowerfilters so I delite the upperfilter and restart the computer, but it does not work.
So I can reinstall it somehow and how can I do?

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}
Be careful it can be many instances of the registry subkey that is mentioned in step 2.
You must ensure that you are in the appropriate registry subkey before modifying the UpperFilters and LowerFilters values.
To verify that you are in the appropriate registry subkey, make sure that the default data value is the CD-ROM/DVD-ROM and the class data value is CDROM.
3. in the right pane, click UpperFilters, and then click on remove.
4. click on Yes to confirm the deletion of the UpperFilters registry entry.
5. in the right pane, click LowerFilters, and then click on remove.
6. click on Yes to confirm the deletion of the LowerFilters registry entry.
7. exit the registry editor and then restart the computer.

    Help us understand what "I lost the ability to restore the system" actually mean for you...

    Are you unable to launch/open the system restore?
    Are you unable to create a new Restore Point manually?
    Your system restore calendar is empty dates?
    You preform a restore and get a message that has failed or nothing has changed?

    If the restore in safe mode will not do, keep reading:

    It would be useful to know a few things about your system:

    What is your system brand and model?

    Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..

    The question was preceded by a loss of power, aborted reboot or abnormal termination?  (this includes the plug pulling, buttons power, remove the battery, etc.)

    The afflicted system has a working CD/DVD (internal or external) drive?

    You have a genuine XP installation CD bootable, which is the same Service as your installed Service Pack (this is not the same as any recovery CD provided with your system)?

    What do you see (exactly) that you don't think you should see, and when you see it?

    What do not you think that you should see?

    If the system works, what do you think might have changed since the last time it did not work properly?

  • 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 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

    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.
