Hi there, I can only post what others have tried and had some success with -
CJ posted what worked for him -
For me this was the solution:
1. Click Start, on "Start Search", type "cmd" (without quotations mark) and right click
the command prompt icon select Run as Administrator.
2. In command prompt, type the following command and Enter: regsvr32 wintrust.dll
If this doesn't work for you try the following:
1. Disable any Firewall, Antivirus, download accelerator software.
Firewalls and Antivirus programs are 3rd Party (non-Microsoft) Programs, and although they
are mostly effective in protecting your computer from Viruses and Computer hackers, they
do fail to take into consideration program installations. The nature of these programs is
that they scan everything on the computer, making sure to try and stop any virus-like
When you visit Windows Update and download, and most importantly install any of the
updates, the update installation is always battled by the Antivirus and Firewall until the
Antivirus clears the program of being a virus. In most cases, this is harmless and the
Update installation goes through successfully. Occasionally, the Installation gets
corrupted, and a process during the install is stopped, or interfered with by the
For this reason, we suggest that you disable any Antivirus or Firewall software while
trying to install updates from Windows Update.
2. Verify the Language Settings
2.1. Start Internet Explorer.
2.2. Click "Tools", and then click "Internet Options".
2.3. Click the "General" tab, and then click "Languages".
2.4. In the "Language" list, make sure that the operating system language
version is included. If the operating system language version is not on the
list, click "Add", click the language in the "Language" list, click "OK",
click "OK", and then click "OK" again.
3. Reset Internet Zone Security
3.1. Start Internet Explorer.
3.2. Click "Tools", and then click "Internet Options".
3.3. Click the "Security" tab, and then in the" Select a Web content zone to specify its
security settings" box, click "Internet".
3.4. Click "Default Level", and then click "Apply" to set this zone to Medium security.
3.5. Click "OK".
4. Verify that the Date and Time Are Set Correctly
4.1 In the bottom right corner of your screen, double click the time. This will open the
Date and Time Properties window.
4.2 Please check that all details are correct including the year, the Time zone and that
AM/PM is set correctly.
4.3 Click OK.
If the problem persists despite performing above troubleshooting steps, I'd like you to
perform below guidelines to download and install a new Windows Update Agent as the current
one might be corrupted.
1. Open Internet Explorer and paste on address bar
(for 32 bit) or
(for 64 bit)
2. A box will prompt to save a the Windows Update Agent file, save it on the Local C:
3. Click Start, on "Start Search", type "cmd" (without quotation mark), right click the
command prompt icon and Run as Administrator.
4. Type c:\WindowsUpdateAgent30-x86.exe /wuforce in the command prompt and Enter.
5. Follow the instructions to install the Windows Update Agent.
6. Please restart the computer after the installation.
7. After restarting the PC, click on Start and choose Windows Update and it will open a
new Internet browser.
8. A box will prompt asking permission to install the Windows Update software, click
Install and proceed to download the updates.
If it still fails, type the following commands in command prompt, pressing ENTER after
net stop cryptsvc
ren %systemroot%\system32\catroot2 oldcatroot2
net start cryptsvc
Hope this works for you too!

If you would like to perform the in-place upgrade, let's refer to the following steps.
