Something on your computer is preventing Exam4 from installing correctly.

The mostly likely program is your security software. In some cases AOL DataMask is the culprit and should be uninstalled. 

  • First uninstall the Exam4 software you already have installed.
  • Then disable your security software and re-download, then install Exam4.
  • Run a practice exam.
  • Re-enable your security software and try another practice exam.
