ZoomText Start-up failure and solution.

Forthcoming Startup Failures in ZoomText 10.1 and other Ai Squared Software products expected on or around January 26th. 


The digital certificate used to certify newer ZoomText and Window-Eyes software products has been compromised. As a result, our certificate will be revoked on or around January 26th, which will result in startup failures for the following Ai Squared products.

Affected Ai Squared Software Products

When attempting to start the following Ai Squared software products, the product will fail to launch and display a Windows error message: "A referral was returned from the server"

  • ZoomText Magnifier v10.1: Build numbers 10.10.8 through 10.11.6
  • ZoomText Magnifier/Reader v10.1: Build numbers 10.10.8 through 10.11.6 
  • ZoomText Fusion v10.1: Build numbers 10.11.1 through 10.11.5
  • ZoomText Keyboard v4: Build numbers 4.0.0 and 4.1.0
  • Window-Eyes v9.5: Build numbers 9.5.1 and 9.5.3

When attempting to start the following Ai Squared software products, the product may launch even though the certificate has been revoked. Anti-virus utilities may detect the invalid certificate and block the software from running.  

  • ZoomText ImageReader v1.2:  Build numbers 1.2.16106
  • ZoomText Voices (language packs) v1.0: Build numbers
  • Vocalizer Expressive v1.3 (for Windows Eyes): Build numbers 

Note: Inspection of the certificate will show that the certificate is invalid. Inspection and validation of certificates is a process performed by some organizations.

Solution (software updates)

For each of the affected products, software updates incorporating a new digital signature will be released and available for download at this link http://www.aisquared.com/CertificateFix/ prior to January 26th.

Warning When Disabling Security Options

Ai Squared strongly recommends against disabling these security options. Various websites provide steps for disabling Windows security options with the expectation that unsigned software executables will start and run. Disabling these security options will not fix these problems for the ZoomText and Windows Eyes products and may compromise security and protection from malware. 


We apologize for the inconvenience this issue has caused you, but assure you we are doing everything possible to rectify this matter as soon as possible. To minimize downtime, we encourage you to update your software as soon as possible.

If you have questions or require assistance resolving this problem, contact the Ai Squared support team at (727) 803-8600 option 2 or support@aisquared.com.
