Hello Spankyinc,

Thanks for posting on the Community Forums of Microsoft Vista.

I recommend to create a system manually, Restore Point so that in this case, a problem occurs when performing these steps, you can always perform a system restore.

Try to create a new user profile and try to install Windows update and check if the update works fine.

Create a new user

1. click on start, type Control userpasswords in the start search box, and then click Control userpasswords in the list programs.

2. click on manage another account.

If you are prompted for an administrator password or for confirmation, type the password, or click on allow.

3. click on create a new account.

4. in the new account name box, type a name of single-byte characters, click Administrator, and then click on create an account.

5. click on the user account that you created in step 4.

6. click on create a password.

7. in the new password box, type a password, retype the password in the area confirm the new password, type an indication of password in the Type a password hint box, and then click on create password.

Once you have a new user accounts check if you can install updates.

Access the link below for more information on how to solve the error message when you try to install Microsoft Update on a Windows Vista-based computer: "cannot install Microsoft Update on the computer.

If the steps above fail, access to the link below and run repair to reset the Windows Update components. It could help us solve the problem of Windows Update.

Later, download the latest version of Windows install 4.5 on your desktop and try to install it. Install the new version of Windows install could help us solve the problem of the installer that you are facing.
