Hi

I got the answer to this question from previous asked questions and answers detail.

It was because of IE7 the solution is to uninstall IE7 using the following command on the START -> RUN

%windir%\ie7\spuninst\spuninst.exe

This uninstalled IE7 and makes it so that you can reinstall it later.

It worked for me
