Rekall can be obtained from the following location:

https://github.com/google/rekall/releases

Rekall supports the following Operation systems:

• Microsoft Windows XP Service Pack 2 and 3
• Microsoft Windows 7 Service Pack 0 and 1
• Microsoft Windows 8 and 8.1
• Microsoft Windows 10
• Linux Kernels 2.6.24 to most recent.
• OSX 10.7-10.12.x.
