TestComplete creates and uses temporary files during test runs. The free disk space required by TestComplete depends on your project size. You need at least 500 MB of free space on the system disk to run small projects, and 1-2 GB of free disk space to run large projects.
Please pay attention to the free disk space before running tests. If your system disk runs out of free space during a test run, TestComplete can malfunction. For example, TestComplete may stop responding to your commands, may not generate test events, the panel layout may get broken, and so on.

Virtual machines like Microsoft Virtual PC or VMware Workstation use a lot of system resources. Typically, applications run slower on virtual machines than on desktop computers. The more virtual machines run on a computer at the same time, the slower they are. To use TestComplete on a virtual machine, use a high-performance host computer that exceeds the recommended requirements to ensure the virtual machine has good performance.
|You need a Floating User license to use TestComplete on a virtual machine. For more information, see Using TestComplete on Virtual Machines.|
