I'm creating a thread about this problem rather than risking it being overlooked in the thread with a misleading titled, where the people who've posted might think that the problem has already been addressed. During installation of the modified driver, the installer "failed to load detection driver", and this happens. It practically freezes up after that. Guess I wasn't homefree. The problem might be caused by my laptop (Thinkpad T500) having switchable graphics with one being the ATI card and another an Intel something-something. Though the ATI was the one switched on during installation - obviously.
