How to fix Microsoft bus driver error while installing Realtek HD audio driver

I was getting "Microsoft Bus Driver should be loaded in your system before installing Realtek HD Audio Driver !" error message while installing my Acer Aspire 5051 laptop audio driver on Windows XP SP3.

Related information regarding this issue on Microsoft support site: http://support.microsoft.com/default.aspx?scid=kb;en-us;835221

Fix:

  • Download the hotfix at Microsoft here.

    The hotfix download link will be sent to your email address. Be sure to add email address hotfix-at-microsoft.com (replace -at- with @) or the domain microsoft.com to your safe sender list (whitelist). This will prevent the email from going to your junk folder. The email message also contains password to extract the hotfix file.

  • Run the hotfix after downloaded.

  • Download the newest driver here.

    It seems Realtek has moved the content of the page, see this url for the newer version, its version R2.08 at the moment.

  • Run the downloaded driver.

That should fix your audio driver installation.

what is the password for that microsoft zipfile

I believe the password sent along with email message from Microsoft.

when i put that password on that screen it does nothing

It should auto extract the file. Try extract the file manually using 7-Zip or WinRAR. Right click on the zip file > Open With > 7-Zip / WinRAR, and extract manually from there.

I believe you need to redownload the zip file. I'm sorry, I can't give you my zip file password because every zip file password is unique, my zip file password won't work on your zip file.

This is for SP3. Doesn't work for you?

my system is showing virtual memory miniium too low .heip me with this

When I runs the hotfix I got an error that says something like

the setup noticed that the service pack version of this system is newer thant the files im trying to install. There is no need to install this setup.

I got SP3 and the latest driver from Realtek HD Audio 2.46 and it doesnt work.

it doesnt do anything, the error is still coming up.

Windows XP SP3.
hotfix 888111 couldn't be installed, like marco Polo wrote..
