I'm going to try this part;
Click
Start, click
All Programs, and then click
Windows Update.
On the Windows Update Web page, click
View update history. A window opens that shows all the updates that have been installed or that have failed to install on the computer.
In the
Status column of this window, locate the update that failed to install, and then click the red X.
When clicked, a new window will open that displays the installation error code.
Once you have found out the particular update:
Go to the
Microsoft Downloads website. Type in the update number (KBxxxxxx) in the search box and press enter. Then click on the link for the specific update and click the
downloadbutton. You will get the option to run or save the download,
save it to your PC. Once it has completed downloading you will get an option to run, open folder, or close. Make sure all other applications are closed and select the
run option. (If you close this window or need to attempt to install again, just go to the location the file was saved to and double-click the file. This will begin the install process again.)
If the manual install fails, try turning off UAC, then attempt the install again. Click
HERE for instructions to turn off UAC.
