Forthcoming Startup Failures in ZoomText 10.1 and other Ai Squared Software Products

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 – Build numbers 10.10.8 through 10.11.6
  • ZoomText Magnifier/Reader v10.1 – Build numbers 10.10.8 through 10.11.6

  • 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attempting to start the following Ai Squared software products, the product may launch even though the certificate has been revoked.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 Window-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.

Warning When Disabling 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 Window-Eyes products and may compromise security and protection from malware. Ai Squared strongly recommends against disabling these security options.

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.
