I do not know why I did not answer your question before. I may not have understood what you were asking.
I am not sure what you mean when you say that your computer does not recognize Internet Explorer.
If you mean that when you click on a link that Internet Explorer does not open, then Internet Explorer is probably just not set up as the default browser. The easy way to correct this is to go to Start - Programs (or All Programs) and click on the Internet Explorer icon. Internet Explorer should detect that it is not the default browser and ask you if you want to make it the default browser. Answer yes. If that does not happen, you will need to click on the Make Default button on the Programs tab of the Internet Options item of the Tools menu in Internet Explorer.
If that is not the problem but instead the problem is that when you click on the Internet Explorer icon in Start, it does not start, then I would suggest going to Microsoft's website (http://www.microsoft.com
) and either download and install Internet Explorer from the Downloads section or see if you can find a solution there.
