Im using *iehta instead of *iexplore but got some error

a popup with message

"cannot find file:///C:\DOCUME~\Local~\Temp\custo...core\Blank.htm l?start=true make sure the path or internet address is corret"

when ok is clicked.. another popup with scripterror messge says "an error occured in the script" and emtpy test runner is opened. server is showing launching IE hta log...

when *chrome is used instead of *iehta, script is exectuing fine.

Pls why is it working for chrome not for iehta..
