Old operating systems
If you are using an old version of Windows or MacOS, you may want to check the compatibility of your system, and if required use an older build of VirtuaDJ.
Note: It is highly recommended to keep your operating system up to date, as deprecated OS have a higher risk of malware. Also, new features and fixes are not available in VirtualDJ's older builds.
But, some older DJ hardware may not be compatible with the latest available Operating systems. Before upgrading, you should check the manufacturer's websites to ensure that all hardware that you will be using (Sound cards, MIDI controllers, etc.) is compatible.
