SYMPTOMS
After you install Internet Explorer and attempt to start the program, an MS-DOS command prompt window is opened instead of the Internet Explorer browser window.



CAUSE
This behavior occurs if the Internet Connection Wizard (ICW) is not installed properly during Internet Explorer Setup.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this issue, use the appropriate method.

Method 1
Remove the installed components key for the ICW component and reinstall Internet Explorer:  Click Start, click Run, and type regedit, and then click OK. Locate the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{5A8D6EE0-3E18-11D0-821E-444553540000}

 Right-click the Installed Components key, and then click Delete. On the Registry menu, click Exit. Reinstall Internet Explorer.</ol>

Method 2
Manually install Internet Connection Wizard: <ol> Click Start, click Run, and type regedit, and then click OK.</li> Locate the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{5A8D6EE0-3E18-11D0-821E-444553540000}

</li> Right-click the Installed Components key, and then click Delete.</li> On the Registry menu, click Exit.</li> In Windows Explorer, click File, point to New, click Folder, and then create a temporary folder on drive C called ICW.</li> Extract the contents of the Icw95.cab file into the newly created ICW folder using the Extract command-line tool (the Icw95.cab file is located in the folder where you downloaded Internet Explorer 4.0x). For additional information about using the Extract tool, click the article number below to view the article in the Microsoft Knowledge Base:

129605 How to Extract Original Compressed Windows Files

</li> Click Start, click Run, and then type the following command:

rundll32 advpack.dll,LaunchINFSection c:\icw\icw95.inf,defaultinstall

NOTE: The .cab and .inf files in Internet Explorer 4.0x are named Icw95.cab and Icw95.inf. In Microsoft Internet Explorer 5.x, the file names are Icw.cab and Icw.inf. This command line needs to be modified accordingly, depending on the version of Internet Explorer.</li></ol>
