I been still surviving on IE6 until recently (as I use most of the time Opera or Firefox, I never bother to upgrade IE). But as I was playing with Silverlight, I need another browser to test my silverlight applications other than Firefox2. Upgrade is painless (you need to restart though at the end).

 After that, any links from my  Yahoo messenger were not working… same the case with Visual Studio 2005/2008…. I guess infact any attempt to launch a webpage from outside the browser was unsuccessful….. 

How to fix it….. my first guess was may be IE7 deleted or moved IE6 executable (Not replaced….as it wont be problem)…… and all these applications keep trying to lookup IE6 ………..  

Well…. I was wrong……  what happend was … IE6 was set as default browser at the time IE7 was installed and IE7 is not set automatically as default browser…….may be it asked me….I dont remember….. so all these applications are trying to launch default browser app…….without much success………..

So to Fix, simply launch IE7…. go to Tools –> Internet Options —> Programs  and Make IE7 as default browser……. that should fix all these broken links…………
