Solution 2:

Don't.

Seriously.

To clarify: It's okay to install IE6 for testing purposes or the like. But that's probably best done in the sandbox of a VM. Do not make IE 6 the default browser on your machine. Nothing good can come out of that.

Solution 3:

IETester will do what you want ...

However I would have a talk with your lecturer.

I would have serious concerns with any course syllabus that requires downgrading back to a browser that was released in 2002, because what they are teaching would no longer be relevant.

The syllabus should be updated to use a current version that confirms with ECMA standards.
