AccessBridge error

An unexpected error has occurred: Assistive Technology not found:

Assistive Technology Not Found Error Notification

Customers running any program that has the Java Access Bridge feature enabled may see this error when attempting to run the PaperCut User Client software. We’ve seen this issue with ImageNow from Perceptive Content solutions, but this is not the only app that might cause this. This error may also be caused by other ‘screen reading’ applications.

The Cause

Since PaperCut changed Java Runtime Environments (JRE) for version 19.0, the instance of Java that powers the User Client Software has been incompatible with the Java Access Bridge accessibility features. When the Access Bridge is installed on the same machine as the User Client Software, it changes a config file and causes an error when our JRE attempts to read it.​​​​​​

The Solution

The best fix for this problem is to disable the Access Bridge technology in the Java configuration files. To do this, follow these steps:

  1. Navigate to C:\Users\<username>
  2. Open the file called using a standard text editor (Notepad is fine)
  3. Find the following lines in the config:
    2. screen_magnifier_present=true
  4. Add a hashmark (#) in front of theses lines
  5. Save your changes to the file, restart the User Client Software

GNOME.Accessibility error

Some customers running the PaperCut User Client on linux with various versions of Oracle Java and OpenJDK users have reported an error of:

An unepected error has occurred: Assistive Technology not found: org.GNOME.Accessibility.AtkWrapper

If you have no requirements to use this module you can modify /etc/java-$version-openjdk/ and comment out assistive_technologies=org.GNOME.Accessibility.AtkWrapper
