PWTK-2024 Virtual Machine image is the same irrespective of which host operating system is used (Linux, Mac OS, or Windows). The virtual machine depends on the VirtualBox virtualization software (version 7.0) and is based on Debian OS.
Hardware requirements
A computer (laptop or desktop) must support virtualization and have about 10G of free disk space.
Installation instructions
To install PWTK-2024 Virtual Machine follow these steps:
- Download and install VirtualBox (click a large blue "Download VirtualBox 7.0" button therein).

Changing the number of CPUs
If your computer has several CPUs then you can increase the
number of CPUs that PWTK-2024 Virtual Machine will use
as to make the calculations run faster. This can be done as
follows: close the PWTK-2024 virtual-machine and in the
VirtualBox Manager select the PWTK-2024 Virtual
Machine but do not start it. Then press the Settings
button and in the window that appears select System tab
and increase (or decrease) the number of CPUs accordingly.
Troubleshooting
On some laptops virtualization is disabled by default. If you encounter any issues, this is the first thing to check. In general you should reboot the system, enter the BIOS and search for a virtualization option and make sure it is enabled. Some general instruction on how to do this are available here.
Black screen issue
If you get a black screen, you may need to change the video
memory in the Settings. Close the PWTK-2024 Virtual
Machine and then in the VirtualBox Manager select
the PWTK-2024 Virtual Machine but do not start it. Then
press the Settings button and in the window that appears
select Display tab and change (increase) the Video Memory.
