Kapture Software Support
Where can I find support on Keeler Kapture software?
Visit the Keeler YouTube channel to find support videos on Kapture Software.
There is no camera to connect.
The Kapture software is loading, but there is no image being displayed and the camera connect button is not there. In the device manager uEye225 appears as a usb device, but the camera itself is not appearing as an imaging device. The workstation needs adding – if the software is installed and run BEFORE licensing a workstation with our slit Lamp as a device is automatically added – if you install and license before running Kapture a workstation needs to be added manually.
A workstation is basically the device configuration for the PC – it is easy to add – the best way is to watch our short video
The live video seems to be slow
It is likely to be a hardware or USB speed problem rather than a camera or software issue. Check the following:
- The PC has an intel processor and chipset
- You are using one of the rear USB ports
- The USB cable is less than 5M in length, we recommend 1.5m
- There are as few as possible USB devices attached
- All the windows energy saving features are disabled
Kapture looses it's license
Users activating the licence need to have local administrator rights. Changing the system date and time can disable the licence
Some anti-spyware and virus scanners can cause the loss of the license. Disable them (on the registry if possible).
Some hardware changes can affect the licence – for example motherboard, hard drive etc.
If Kapture is shut down before selecting a ‘close without changes’ tab a new serial code will be generated and the activation code will not work.
I get a login message: ‘Systempointer needs resetting by admin’
This indicates the path to the image tables is incorrect or is not available. Check the settings in admin for the data directories.
If this fails contact Colin West for a software fix, firstname.lastname@example.org
Does Kapture run on Windows 7 & windows 8
Yes, Kapture will run on Windows 7 & 8 32 & 64bit
Does an imac work for kapture
We do not recommend running Kapture on an iMac with Windows but yes it should work, though it is not supported so if any issues do occur we may not be able to resolve them. Boot camp would be the preferred route to running Windows on the Mac
Can I recover deleted patients or episodes
Yes – when records are deleted by a user they are hidden from the database but not physically deleted. The system administrator can go to the set up menu – select the 5th icon from the left and click on the show deleted records icon and either restore the records or permanently delete them to recover disc space. Note – if they are deleted from the admin screen they are permanently deleted.
The user want to capture images with one click and does not want to use the freeze frame function in Kapture
Standard Kapture a freeze frame function to select the best image after you have pressed the capture button on the joystick.
The user has to press the capture button twice, once to freeze the image, then a second time to select the best image from the video frames stored in RAM, or just click again to select the current image.
If the user wants only the last image, a "double click" on the capture button will achieve this.
An alternative to this would be to fit a usb footswitch and use it to capture the image with a single click.
When I add a patient I get the message: Patient Duplicate Details
The patient ID is very important in Kapture as this the unique identifier for your patient. It is unique and cannot be changed.
the system will detect if a patient is added that already may exist when it check the following fields in the database:
- Date of Birth
If there is already a patient in the database which the same details, Kapture will show the Patient Duplicate Details message and will show the patient the detail with the known patient ID.
The user can check if he has made a typing error with the patient ID and cancel the add and go to the existing patient, or he can add the patient anyway.
So this is NOT an error message and does NOT stop you to add the patient it is just a warning to inform that a patient with the same details already exist.
Can I use Kapture on a PC with user right less than Local Administrator
Yes the user needs full rights to the Kapture folder and its included folders. (and the data folder if this is on a different location)
How do I activate a Kapture License

The image is greatly enlarged in the Ann/Msr and Rel screen
When you switch to the Annotation / Measurement / Relative the screen selected image will be shown as full size (100%). i.e. pixel for pixel. This as we have to draw on top of the image using a layer so it has initially to be set to 100%.
With high resolution images this can cause a problem, you can change the size of the image with the scroll wheel of the mouse
When I connect the camera for the first time to Kapture I get an error message
This is normal until the camera has been ‘registered’ by the software – just click OK and it should go to live view.
If the software has just been installed – do let the PC have a few moments after plugging in the camera for the drivers to load.
When I add a patient, Kapture informs me that the patient already exists.
I cannot find in using the browse or other search options
When you delete a patient/episode then the patient or episode information is placed a recycle bin of the database. This is for extra security to prevent loss of important medical data.
The user ‘Admin’ can recover a deleted patient/episode information or delete (purge) it permanently.
When you add a patient then the Patient ID has to be unique. If you add a patient who has been deleted so (placed in the recycle bin) with the same ID then you cannot add and find it.
You have 2 solutions:
- Ask Admin to recover the patient
- Ask Admin to delete/purge the patient
When I go to the image capture screen there is no camera visible
Check if the workstation name in admin is the same as the name of the computer. Just press OK when adding the workstation to get the correct workstation name.
Is the save button active? If not then the user has no ADD rights. Check in the admin, user setup if the user has ADD rights also make sure image capture form view only is NOT selected.

Check the path in the C:\Kapture\local.ini and the Kapture.ini file (which is at the same location as the database)
Can Kapture run on a Apple Computer/laptop
We do not recommend running Kapture on a Mac with Windows but yes it should work, though it is not supported so if any issues do occur we may not be able to resolve them. Boot camp would be the preferred route to running Windows on the Mac
I cannot play video on an XP machine
You need to install “ffdshow tryout” for any XP users wanting to capture video if they have the appropriate version of Kapture that includes video capture.
Play back of video requires that your PC has a codec for MJPG installed. This is standard with Windows 7 but not with Windows XP. You may have one already installed in XP depending upon which packages you have installed. If you need one you can install the ffdshow-tryouts package from ......
I can’t run capture on a windows 7 PC
Dot net framework 3.5 is required with Windows 7 SP1
The camera connection is intermittent
Check the connections to the USB hub on the Slit Lamp base – if necessary bypass the hub and connect the camera to the PC. If the connection is OK then it is possible one of the USB connections has been damaged.
The exposure and trigger functions don’t work
Try changing the settings by using the keyboard shortcuts – ctrl + alt + F8/9/10 for trigger, longer exposure and shorter exposure times. If the functions work on the keyboard then the trigger board on the Slit Lamp may have become damaged.
