Try going to the Pentax website and see if they have a Windows 8 update for the software for your type camera. Many manufacturers update software as new Operating Systems come out.  Usually, you can just download it to your computer and most of the time it's free. Hope this helps you.
Sorry if I have posted this in the wrong place.  Please bare with me as I am not computer savvy with terms. I am getting a Del with Windows 8.  I know nothing about Win 8. I have  a Pentax Digital Camera and a software CD came with it.  I needed to install this program in my old computer in order to transfer pics, etc. to that computer. The CD states that it is for Windows 2000/XP.  I now have XP. Will I be able to install this software CD onto the new computer with Windows 8?  My concern is that I won't be able to do this, and then my camera will not work with the new computer. Thanks. Marcedes        
New to Windows 8
