This Runtime Error R6025 –
pure virtual function call appears on the users screen.
It has happened to two customers so far,
the first was shooting 72 JPG + RAW images. The second was shooting many 3D
images on a high-resolution camera.
Cause / Solution:
The computer is being taxed too hard and cannot take it. Use a stronger computer. Take fewer pictures,
especially in RAW formats.
Note: 72 RAW shows can tax any computer.
Especially with the D810 which is a 30MP camera.
