Just install Windows 64 bit.  New installation.  Whenever I try to open Windows Media Player or Media Center, I get a message that says that "Windows Media Player has stopped working.  Windows can check online for a solution to the problem.

I clicked on "check online for a solution", but nothing came.

I tried to install an earlier version, but was not allowed to do.

How can I solve this problem.

Hi Nick91606,

KERNELBASE.dll is a file system of the operating system.

Method 1

I suggest that you save the file on your computer and check if Windows media player works.

(a) click the Start button.

(b) in the search box, type command prompt.

(c) in the list of results, right-click guest, and then click run as administrator. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

(d) in the type command regsvr32 kernelbase.dll line press ENTER.

(e) close the command prompt

Method 2

If the previous step fails then I suggest that scan you SFC on the computer that would be a system file corrupt on the computer search and replace.

The analysis may take some time, so be patient. Windows allows to fix corrupt or missing files it finds. If the information of the installation CD is required to fix the problem, you may be asked to insert your Windows Vista installation CD.

For more information please visit the link below.

  • Remove the auto to replace new installed XP Pro search function, whenever I try to open transferred files/documents

    Hello all him world-same advisors windows on this forum:

    I thought I had posted this slight question here, but maybe on other forums of Web site...  I could not find in this forum, throughout 50 not possible pages to be sorter for the dates of entry anywhere to locate mines. So, I am apologically, submit again (if I already posted here).

    I prefer my implementation of behaviors on my programmed replacement XP computer to be what I'm used to.  My old computer was XP system (do not know if a Home or Pro).  Whenever I have clicked/open a saved folder and/or its documents/pictures, etc., he immediately opened everything I wanted.  Very simple and the most privileged.

    This computer has been changed by a virus (HDisc has been cleaned) and breath of capacitors (?).  I replaced this computer with a similar XP programmed order.  This computor (Lenovo) is installed with OEM XP Pro (Service Pack 3 2002).  My cleaned documents and records were transferred to this computer.  They are also on my external hard drive. All resettled programs worked / I was able to run everything as I preferred, and I know my game previous changes.

    The new computor will now automatically in the search window (I got rid of this infernal animated dog) whenever I click/point on a folder and or any document in this folder.  I now do a right click to open the menu, scan down to go to search, explore, open and click on open every time I want my stuff with immediate access. I went and variously adjusted/delete/restore items separated and grouped in file search options. No effect I wanted, then it's back to the restored original basis.

    Does anyone have a simple solution for a keen memory private user of documents and folders to open the first time I point to them, without having to the Group of experts through 2-3 additional steps to counter some automatic placement in a research program?

    Thanks for the reply.  Method 1 as fact: click Start, control panel (click appearance and themes is not in this Panel) then you click on options files, display tabs, then erased automatically search box of files network, apply, and then click OK.  No effect.  When I click on registered (non-shared, never networked shared, in a single computer only) folder, the search engine appears and indicates to click on in the box on the left to share.  It brings up a list.

    I want my file to open it in mode icon in place, what it does when I go its just clicked menu to open.

    Method 2: start, press go to run, should have read clicked ok, locate items in step 2 (through the menu items open progressive as indicated), when in the value DWord, when started banging NoNetCrawling he immediately travelled to this window and in box will the number 1, which was already. This spruced up, press OK and the closed registry editor and start box.     Once again, no change in behavior.  Go back to defaul restoration, since it is the basis for me to start without jump my computer up to my forgotten violin.

    Thanks a lot again.  However, responses to my question don't involve any networking computors, shared, wifi /, household D link wireless routers, office or home setting or use dial-up.  It is a computor that whenever I point to a folder, the search procedure starts automatically.  I want this behavior stopped and I want the computer to open the folder and the files it contains right now I click on it (I use the simple click).  Click and open.  Don't click, search, open.

    How can I find my question?   I went to the discussion for XP, all questions and did not find it anywhere among the 50 items recently answered to.  Only it obtained pressing the issue on my e-mail address containing your answer.

    I remember that when I tried to install the driver, there's a message that says that it is said that it is not supported.  I don't know if I reinstalled the older operating system and then the new driver and vista or if there was a button to install the driver, even though it was not taken in charge.  Most likely, I installed the driver on the old XP operating system and then applied the upgrade to Vista. I always run a clean install to clean any spyware etc. The driver supports the X 9 live is what it takes. Use Vista driver is already installed.  I plan to upgrade to windows 7 in January and display the results.
