sorry its solved by me,
Right click on the Start menu, click Run, type Regedit in the Open box, and then click OK.
Browse to
HKEY_CURRENT_USER\Software\Classes\.html
If a default value (Default) has a value other than htmlfile or (value not set), right click on it and select Modify...
Change the value from "ChromeHTML" to htmlfile (or from FireFoxHTML to htmlfile)
Repeat for the .htm, shtml, .xht, .xhtml, .xhtm keys
and Restart your windows
