I recently bought a Nikon D3200 and the files are not supported in lightroom 3 which is the version currently have on my computer. I didnt want to upgrade it yet because i am planning on buying a new computer soon. I tried to download the camera raw 7.0 patch but kept getting an error that says "Update Failed. This patch is not aplicable for you. Please check the help menu in your product for updates." I did check my product and there are no updates avaliable. What should i do?
You should download the free Adobe DNG Converter version 8.6, convert your RAWs to DNG, and then import the DNGs into Lightroom.
Downloading Camera Raw isn't going to help you at all with Lightroom. Lightroom doesn't use the Camera Raw plug-in. If you want support for your camera you will have to upgrade your Lightroom. And you can easily move everything to the new computer as long as you have your images well organized. Otherwise, it could be a challenge to relink your images.
