<p>I recently purchased a Nikon D750. I want to shoot Raw, but my version of Lightroom 4.4 does not support the Nikon D750. According to my research I need at least Lightroom 5.7 edition or newer . I bought and returned 6.0 when I discovered it will not work with my computer with Windows 7 with 32-bit OS. If I use the 6.0 edition I would have to buy new OS software, motherboard and processor. I do not want to because of the expense. If I buy Lightroom 5.0 can I go to the Adobe website an update to 5.7 edition without additional cost? </p>
