Error code 80040154. Class not registered.

To fix this:

The error means there is a problem with the permissions on the registry. The simplest way to fix this is to install the software as the administrator, but you need to modify the permissions on the registry key.

1. Click Start> Run> type regedit and press enter.

2. Navigate to: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlPrintEnvironmentsWindows NT hive.

3. Look for the Windows NT hive on the left pane and choose Permissions.

4. Remember that the system account is in Full Control. You can do this by clicking on the System User on the top and then tick the Full Control check box.

5. Click OK to save the settings and close the regedit window.

6. Reboot your computer before attempting to install again.

Since your computer was unable to check new updates for Windows, you may want to check if you have a good internet connection. Open your web browser and then try browsing some websites and see if your internet connection is stable enough. If the connection seems pretty much stable, try again the Windows Update. If it still does not work, try checking your computer for any possible errors. Use a disk utility tool to check the system. For a much thorough diagnostics on the system, use a disk utility tool like PC Tools Performance Toolkit or Norton Utilities.

You can also try checking your system using System File Checker. Click Start, Run then type sfc /verifyonly then hit Enter. This command will check the integrity of all protected system files. If the scan reported an error, open WINDOWSlogscbscbs.logsfcdetails.txt to see the error details. After checking the details, try attempting a repair by clicking Start, Run then type sfc /scanfile=<path and file name>. For example, sfc /scanfile=C:WINDOWSsystem32iasias.mdb.

Hi Kate Harry 

The error is usually encountered in the absence of apt permissions in the registry. Ensure that you are performing the windows update after being logged in as an administrator. Also check out this Techyv post to get more idea regarding on this issue.
