I don't need just 2 windows(IE) to be opened. More: each IE to run in a diffrent process.(when you look in Taskmng you should see 2 IE).

l3nz's solution solves this problem but added a new problem:
How I close IE when I've done with it? witch I've solved using JavaScript in the file opened in IE.

I've Install Windows Script Host and I still get this error: Can't start ShellWin32::OLE(0.17) error 0x80040154: "Class not registered"
