  Hi Kim,

  I'm not sure he was able to run the program, since access seems to have been refused. From now the error 8007005 is dormant. I still can't use the printer, and I can't install .NET framework 3.5 update with error 80070645. I have done checkdisk and memory test and they can't find any problems.

  Hey Ryan,

  If the list of items that you pasted in your previous post presents the problem registry keys.  It seems that the appropriate permissions for these keys have been stripped.  Here are the steps that you can try to solve the problem.  Please do not forget to mark the thread as "Response" if it solves the problem.

  1. download Windows PowerShell:

  First you will need to download a tool called PowerShell V2 (CTP3) starting from Microsoft Download Center: http://www.microsoft.com/downloads/details.aspx?FamilyID=c913aeab-d7b4-4bb1-a958-ee6d7fe307bc&displaylang=en

  2. install Windows PowerShell:

  Then, double-click the file you downloaded to install the tool.  Please note that you may get a message indicating:

  "Windows PowerShell (TM) V2 (CTP3) remote features may not work correctly in this version of the operating system".  What is expected based on the version of Windows Vista (eg Home Premium).  On this same screen, click on install to continue.

  3. launch the PowerShell:

  Once you have downloaded the PowerShell, click on the start menu and type "PowerShell" in the search field.  Click Windows PowerShell in the result of research for loach tool.  If the tool is running properly, you'll get a window with a blue background, with a command prompt "PS C:\ >.

  4. at the command prompt (PS C:\ >), type each of the following commands (a to f) followed by the Enter key.
  Tip: You should be able to paste each of the commands one by one.  Simply right-click in the window and select Paste.

  a. $acl = get-acl-path "hklm:\software\Microsoft\Windows\CurrentVersion\Component Based Servicing"

  b. $inherit = [system.security.accesscontrol.InheritanceFlags] 'ContainerInherit', 'ObjectInherit.

  c. $propagation = [system.security.accesscontrol.PropagationFlags] 'InheritOnly'

  d. $rule = new-object system.security.accesscontrol.registryaccessrule "NT TrustedInstaller service", "FullControl", $hériter, $propagation, "allow."

  e. $acl.addaccessrule ($rule)

  f. $acl | Set - acl

  (If you get an error message, take a brief description of the error and let me know.)

  6. close the PowerShell window and test Windows Update

  Kind regards

• Vista - Error Code: 80070645 (cannot install the update KB959209)

  I'm currently under that Windows Vista Home Premium with Service Pack 2 installed.

  Windows Update KB959209 was recently downloaded for installation.

  Unfortunately, it does not install and generates Code 80070645.

  I tried to uninstall Microsoft .NET Framework 3.5 SP1 as recommended on many forums in various ways, but I always get an error trying to reinstall it.  It will uninstall programs and features in the control panel and it does not appear in the Windows Installer Clean Up scroll box.

  Can someone please suggest a solution to actually install KB959209, please?

  Thanks in advance,

  Tom Helget

  KB959209 is an option, not the security update. Feel free to hide it.

  Alternatively, you can try to download/install manually: http://www.microsoft.com/downloads/details.aspx?familyid=6c095bba-6100-4ec9-9c54-6450b0212565
