Method 1: Use Windows Update to update Windows and Internet Explorer
Method 2: 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.
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 Windows Live OneCare safety scanner. To use the Windows Live OneCare safety scanner, follow these steps:
Step1:In Internet Explorer, visit the following Microsoft Web site: http://onecare.live.com/scan
Step2:Click Full Service Scan.
Note The behavior that you see on the Windows Live OneCare Web page might be a bit different from what we describe here, but basically this is what will occur. The Windows Live OneCare 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 Windows Live OneCare. To do this, click Download free trial under Get continuous protection for your PC with Windows Live OneCare on the Windows Live OneCare Web page.
Step3:When the scan is complete, try to install Internet Explorer 7 again. To download Internet Explorer 7, visit the following Microsoft Web site:
http://www.microsoft.com/windows/ie/downloads/default.mspx
Method 3:Check for any files that cannot be backed up or updated
This method is rated: Moderately difficult.
To complete this method, follow these steps:
Step1:Determine whether a problem is preventing the files from being backed up or updated. To do this, follow these steps:
a:Click Start, and then click Run.
b: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
Note By default, the Ie7.log file is located in the C:\Windows folder.

d:On the Edit menu, click Find.
e:In the Find what box, type ArchiveFileForUninstall:ArchiveSingleFile Cancelled.
f: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:
Step2: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"
