Protect your patient images before making major changes
Before uninstalling software, deleting folders, clearing storage, changing directories, or moving X-rays, confirm that your patient images and data are safely backed up and can be opened from the backup. If you are uncertain, stop and request assistance first.

Error in XML Document (1, 1)Software configuration or damaged XML file
What it usually means
The software is trying to read an XML configuration file that is empty, damaged, missing, or pointing to an invalid location.
What to try
- Close A2D2 and restart the computer, then try again.
- Confirm that the folder containing your X-rays is still available and that your patient images are backed up.
- If the error continues, use Windows Apps or Add/Remove Programs to uninstall A2D2.
- After confirming your data is protected, remove only the old A2D2 program installation folder—not your X-ray storage folder.
- Reinstall A2D2 into a new program directory rather than the same damaged location.
Patient Select Shows a Path Instead of a NameThe patient's data file may be missing
What it usually means
A2D2 can see the patient folder, but the patient’s .dat information file is missing or incomplete.
Recreate the patient information
- Open the affected patient folder in A2D2.
- Open the File menu.
- Select Enter or Edit Patient Info.
- Confirm or re-enter the patient information and save it.
- Return to Patient Select and confirm that the patient name now appears.
No Imager DetectedWindows or A2D2 cannot communicate with the imager
What it usually means
The imager is not being recognized by Windows, is not available to A2D2, or has a power, cable, driver, or hardware communication problem.
What to check
- Restart the computer and fully power-cycle the imager.
- Check whether the imager appears in File Explorer, This PC, or Device Manager. This helps separate a Windows/hardware issue from an A2D2 software issue.
- Confirm that your installed A2D2 version is appropriate for the computer and imager. Do not change versions until you know what is currently installed.
- Inspect all cables for loose plugs, cuts, kinks, or damaged connectors.
- For a Model 128S, inspect the black power adapter for loose connections or rattling.
- Follow the Imager Connection Error Sheet for additional checks.
Object Not Set to an Instance of an ObjectInstallation, configuration, or .NET component failure
What it usually means
A required software component, configuration value, or compatible Microsoft .NET component may be missing or may have failed during installation.
What to try
- Restart Windows and try opening A2D2 again.
- Record your current A2D2 version and Windows version before changing anything.
- Confirm that your X-rays and patient data are backed up.
- Uninstall A2D2 using Windows Apps or Add/Remove Programs.
- Remove only the old program installation directory, then reinstall into a different program directory.
- If the error remains, the computer may need a compatible A2D2 version or the required Microsoft .NET component. Version 10.5.5 includes the .NET component used by that release, but it may not be the correct version for every imager or workflow.
Error Message 8195Storage path, permission, capacity, or version problem
Common causes
A2D2 cannot write to or communicate with the primary storage location, the destination is full, or the installed software version is incompatible with the imaging hardware.
What to check
- Confirm that the primary X-ray location is connected and accessible from Windows.
- Check that the Windows account and A2D2 have permission to read and write to that location.
- Check the free space on the primary drive, server share, external drive, or NAS.
- If
C:\A2D2_Datamust be cleared, first confirm that it contains only temporary cached copies and that the original X-rays exist, are backed up, and can be opened elsewhere. Never assume it is safe to empty. - If storage must be moved, plan and verify the new external, server, or NAS location before changing A2D2’s default directory.
- Confirm the A2D2 version and imager model. Older software may not communicate with newer imaging hardware.
