Installing Internet Explorer 7 on XP SP3

November 2016

The Windows XP Service Pack 3 (SP 3) is a network installation package that is useful for installation and download on multiple computers that are connected on a network. Ideally, this pack must be installed after the installation of Internet Explorer (IE) 7 due to compatibility issues. Users can, however, install IE 7 even if the XP SP 3 already exists in the system. For this, modifications in the registry are required to be done by using Regedit. It is important to keep a back up of the registry before making changes in the configuration. This can be done through the export of the registry so files can be accessed.


Internet Explorer 7 is not compatible with Service Pack 3 is already installed. You should however install SP3 after installing IE7.

Here is how to install IE7 if SP3 is already installed on your PC. This process requires you to modify the registry as shown below:
  • Go to Run in the Start menu
  • Type regedit then click OK
    • Note: It is recommended that you make a back of your registry before any configuration. To do so, go to File > Export and save the registry somewhere you can find it.
  • Then scroll to the key:

  • Right-click the key and select Permissions
