I have a K20D and I installed the photo editing software that came with it on Windows XP Service Pack 3.
I had no problem with this software but I have since bought another computer with Windows7Home Premium 64Bit. I cannot install this software on Windows 7. I know there is an updateentax Photo Browser 3 and Pentax Photo laboratory 3 but these updates have no effect on the windows software.
Can anyone suggest away round this problem.
best wishes
