SYMPTOMS
When you try to install Microsoft Update on a Windows Vista-based computer, you may receive the following error message:

Could not install Microsoft Update on the computer.

[Error No. : 0x80004005]



CAUSE
This problem may occur if one of the following conditions is true:
 * The user account that is used to install Microsoft Update does not have administrative credentials.
 * The account name that is used to install Microsoft Update contains double-byte characters. For example, this problem occurs if the account name contains kanji characters, hiragana characters, or katakana characters.



RESOLUTION
To resolve this problem, create an account name that contains only single-byte, alphanumeric characters. Then, grant administrative credentials to the new account. Log on to Windows Vista by using the new account, and then install Microsoft Update. To do this, follow these steps in the order in which they are listed.

Create a new user

 * 1) Click Start vistastartbutton.jpg], type Control userpasswords in the Start Search box, and then click Control userpasswords in the Programs list.

 * 2) Click Start, click All Programs, and then click Windows Update.

Delete the account that contains the single-byte character name
After you have finished installing Microsoft Update, delete the user account that you created for this task. To do this, follow these steps:
 * 1) Log on to Windows Update by using an account that has the original double-byte character name.
 * 2) Click Start, click Control Panel, and then click Add or remove user accounts.
 * 3) Click the user account that you want to remove.
