You can temporarily disable acceleration to allow a virtual machine to successfully run or install software.

In rare instances, you might find that when you install or run software in a virtual machine, the virtual machine appears to stop responding. Generally, the problem occurs early in the program’s execution. Often, you can get past the problem by temporarily disabling acceleration in the virtual machine.

This setting slows down virtual machine performance, so only use it for getting past the problem with running the program. After the program stops encountering problems, deselect Disable acceleration. Then you might be able to run the program with acceleration.

You can enable and disable acceleration when the virtual machine is running.
