How to use shell execute to open internet explore

[maapi]

I was using ShellExecute to open internet explorer in my TAPI application for Avaya IP Office it was working fine in windows XP and windows 7.
It is not working in windows 8 and windows 8.1.
I am using the following code ,
ShellExecute(NULL, "open", "C:\Program Files (x86)\Internet Explorer\iexplore", "

http://testurl"

+CID,NULL, SW_SHOWMAXIMIZED);

also i tried :

ShellExecute(NULL, "open", "iexplore", "

http://testurl"

+CID,NULL, SW_SHOWMAXIMIZED);



what changes do i need to do to make it work in Windows 8.1?


iam happy i am here...
