excerpt from I receive a warning: The browser cant be used in virtual machine software such as Virtual PC, VMWare and Parallels.
"To maintain the academic integrity of an exam, students are not permitted to run LockDown Browser Student Edition when a virtual machine is detected on the system.
Anti-virus software can sometimes result in this type of error when running small "sandbox" VMs. Shutting down the anti-virus software temporarily while you use LockDown Browser may help.
If the deadline for an exam is near, you may want to consider locating another computer, Mac or Windows, with LockDown Browser. There is also LockDown Browser for iPad, if allowed by the instructor."
