error code 0x80246008 - tried some steps but was not able to conti

I have tried steps that were given to me through this forum.

But i can't do the following steps: the black box dissapears??

Step 3:

Go to Start -> Run, type in Reghedit and press Enter. Navigate to:
HKEY_Local_Machine\Software\Microsoft\WindowsNT\Cu rrentVersion\SvcHost
In the right pane, double-click to open the netsvcs key. Under Value Data,
add BITS
to the list of services. Click OK. Exit the registry. Restart the
system and check out Windows update again. If still fails, proceed to Step 4:

Step 5:
Go to command prompt (Start -> Run -> type in CMD and click OK), run the
following command:
Reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\BITS\Parameters
/v
ServiceDll /t REG_EXPAND_SZ /d %windir%\System32\qmgr.dll

(All one line. Since this command is complex, please copy it and right click
on the
Command Prompt window -> Paste, then Enter.)

Then please restart the PC and retry Windows Update

If the above command does not work, please try the following again:

Reg add HKLM\SYSTEM\CurrentControlSet\Control\BackupRestor e\FilesNotToBackup

Restart the PC and retry Windows Update. If still no success, go to Step 6:

Step 6:

Go to C:\Documents and Settings\All Users\Application Data\Microsoft\Network

(Note: Application Data is a hidden folder, so ensure you go to My Computer
->
Tools -> Folder options -> View, check Show hidden files/folders)

Delete the Downloader folder.

Here I found the Documents and Settings\All Users but not the application
data folder.

please help me fix this problem.
