Let me fix it myself


Sample command to reset security settings

Note After security settings are applied, you cannot undo the changes without restoring from a backup. If you are uncertain about how to restore your security settings to the default settings, you must make a complete backup that includes the System State (the registry files). Items that are reset include NTFS file system files and folders, the registry, policies, services, permissions, and group membership.
To restore your operating system to the original installation default security settings, follow these steps:
  1. Click Start, click Run, type cmd, and then press ENTER.
  2. In Windows XP, type the following command, and then press ENTER:
    secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose
    In Windows Vista, type the following command, and then press ENTER:
    secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose
    You receive a "Task is completed" message and a warning message that something could not be done. You can safely ignore this message. For more information about this message, see the %windir%\Security\Logs\Scesrv.log file.
Note In Windows Vista, the Defltbase.inf file is a Security configuration template for the default security. You can view the settings for this file in the following location:
%windir%\inf\defltbase.inf
To verify that the method worked, try to install Internet Explorer 7 again. If you need to download Internet Explorer 7, go to the Microsoft Download Center:

Next steps
After you run this Microsoft Fix it (or complete these manual steps), standard user accounts may no longer appear on the log on screen when you start your computer or try to switch users. This occurs because standard user accounts are removed from the Users group when you reset Windows security settings. To add the affected users accounts back to the Users group, follow these steps:
  1. Click Start, and then All Programs. Or click Programs.
  2. Click Accessories, and then click Command Prompt (Windows XP). Or right-click Command Prompt, and then click Run As Administrator (Windows Vista).
  3. In the Command Prompt window, type net users and then press ENTER. A list of user accounts is displayed.
  4. For each accountname listed in the Command Prompt that is missing from the log on or switch user screen, type the following command and then press ENTER:

    net localgroup users accountname /add
  5. Now go to the "Did this fix the problem?" section.

Method B: Scan your computer for malware

This method is rated: Easy.

How you scan your computer for malware depends on the malware-protection programs that you have installed.

Important If you use your own antivirus and anti-malware software, update the antivirus and anti-malware definition files before you scan your computer.

If you do not know how to update your antivirus and anti-malware definition files, or if you do not know how to scan your computer, an easy and free way to do this is to use the Microsoft Security Essentials safety scanner. To use the Microsoft Security Essentials safety scanner, follow these steps:
  1. In Internet Explorer, visit the following Microsoft Web site:
    http://onecare.live.com/scan
  2. Click Full Service Scan.

    Note The behavior that you see on the Microsoft Security Essentials Web page might be a bit different from what we describe here, but basically this is what will occur. The Microsoft Security Essentials safety scanner is downloaded and installed on your computer the first time that you perform a scan. The scanner will inspect your computer. Then, it will give you results and recommendations when the scan is complete. This might take a while, so be prepared for that.

    Note If you currently have no malware-protection programs installed, you can download a 90-day free trial of Microsoft Security Essentials. To do this, click Download free trial under Get continuous protection for your PC with Microsoft Security Essentials on the Microsoft Security Essentials Web page.
  3. When the scan is complete, try to install Internet Explorer 7 again. To download Internet Explorer 7, visit the following Microsoft Web site:

Method C: Temporarily disable antispyware or antivirus software

This method is rated: Easy.

Note Before you temporarily disable your virus scanner, make sure that the Windows Firewall is enabled. After you complete the steps, enable the virus scanner again.

Antivirus software is designed to help protect your computer from viruses.

Advanced troubleshooting

Method E: Check for any files that cannot be backed up or updated

This method is rated: Moderately difficult.

To complete this method, follow these steps:
  1. Determine whether a problem is preventing the files from being backed up or updated. To do this, follow these steps:
    1. Click Start, and then click Run.
    2. Copy and then paste (or type) the following text in the Open box, and then click OK to open the Ie7.log file:
      %windir%\ie7.log

    3. Press CTRL+END to move to the end of the Ie7.log file.
    4. On the Edit menu, click Find.
    5. In the Find what box, type ArchiveFileForUninstall:ArchiveSingleFile Cancelled.
    6. Under Direction, click Up, and then click Find Next.

      If you find the "ArchiveFileForUninstall:ArchiveSingleFile Cancelled" text, this indicates that there is a problem that is preventing an Internet Explorer 6 file from being saved for uninstall. For example, text that resembles the following in the log file indicates that there is a problem:
      Time_stamp: ArchiveFileForUninstall:ArchiveSingleFile Cancelled
      Time_stamp: DoInstallation:UpdSpCommitFileQueue for AlwaysQueue Failed: 0x4c7 
      If you do not find the "ArchiveFileForUninstall:ArchiveSingleFile Cancelled" text in the Ie7.log file, contact Support.
  2. Reset the permissions for the Vgx.dll file. To set the permissions of the file to the default settings, click Start, click Run, type cmd, and then click OK. At command prompt, copy and then paste (or type) one of the following commands, and then press ENTER:
    • If you are running Windows XP, copy and then paste (or type) the following command:
      echo y| cacls "%CommonProgramFiles%\Microsoft Shared\VGX\vgx.dll" /P BUILTIN\Users:R "BUILTIN\Power Users:C" BUILTIN\Administrators:F "NT AUTHORITY\SYSTEM:F"
    • If you are running Windows Server 2003, copy and then paste (or type) the following command:
      echo y| cacls "%CommonProgramFiles%\Microsoft Shared\VGX\vgx.dll" /P BUILTIN\Users:R "BUILTIN\Power Users:C" BUILTIN\Administrators:F "NT AUTHORITY\SYSTEM:F" "NT AUTHORITY\TERMINAL SERVER USER:C"
  3. Try installing Internet Explorer 7. If Internet Explorer cannot be installed, check the log file again by following the steps in Method D. If the log file shows a problem, repeat all the steps in this method.
  4. If you repeat the process and Internet Explorer 7 still cannot be installed, but the log file is clean, contact Support.
