 Frequently Asked Questions 

1. What operating system do I need to run K3CCDTools?

K3CCDTools runs on the following operating systems:
Windows 95, Windows 98, Windows 98 SE, Windows Millenium Edition, Windows NT 4.0, Windows 2000, Windows XP. Finally, K3CCDTools 3 can run on Windows Vista and Windows 7.

2. I have just tried to load K3CCDTools onto my Windows 95 laptop. When I try to run the program I get:
The K3CCDTOOLS.EXE file is linked to missing export SHELL32.DLL:SHGetSpecialFolderPathA
Shell32.dll (version 4.00.1111) is present in the Windows\System folder.
Does anyone have an idea of what is going wrong?

The error is caused by old version of your Shell32.dll. K3CCDTools requires Shell32.dll version 4.71 or higher.
One of ways how it can be installed is to install Internet Expolorer 4 with Service pack 1.

3. I've tested the camera with my desktop using win98 & K3CCDTools and it works OK.
However, when I try it with my laptop running Win XP Pro and K3CCDTools, the long exposure doesn't work -
i.e. I can change the exposure time and the image still looks the same (no change in exposure).
I've checked port address and my laptop is using LPT1. I set this but it still doesn't seem to work.
Have you got any ideas?

Here are several hints:
1, Do you have gwiopm.sys file installed in your K3CCDTools directory?
2, Do you run K3CCDTools with administrator user rights in Windows XP?
3, You can do an experiment - switch K3CCDTools 2 into normal exposure mode (live preview) and open Port Commander.
Try to send to port values 11111111 -> the picture should be visible
and then 00000000 -> no picture should be visible.
If the test in point 3, didn't work OK, then you may have a problem with parallel port settings.

4. My camera stopped working with K3CCDTools. I can see the camera listed in the device menu;
but the camera doesn't turn on and there is no image (just black). No red light on on the camera.
Before, it used to work ok and when I started K3CCD the camera would automatically turn on
and an image would appear - now it doesn't.

K3CCDTools remembers the camera state when K3CCDTools is closed.
It looks that your camera is not in Preview mode. Just press the Preview button on the main toolbar
or check the Preview menu item in Video Capture menu.

5. What exact K3CCDTools version have I installed?

Start K3CCDTools and select menu Help - About.... The K3CCDTools About dialog appears with exact K3CCDTools version displayed. It also displays your DirectX version number below K3CCDTools version number.
The example show here displays K3CCDTools version and DirectxX 9.0 (

6. Is K3CCDTools 3 compatible with Windows Vista or Windows 7?

K3CCDTools 3 can run under Windows Vista or Windows 7, however, you must set K3CCDTools to run in XP compatibility mode. Find the K3CCDTools.exe program in Windows Explorer or its shortcut, select it and use the right click menu - Properties:

Eventually, you can check the Run this program as an administrator checkbox.

7. What is K3CC AVI codec?

K3CC codec is a special codec for AVI video files which I developed for encoding higher bit depths than standard 8-bit depths for each color channel.
