This page is an archive of all current builds of CrypTool 2.
The builds run on 32 and 64 Bit Windows. Please note that you need the Microsoft .NET Framework 4.0 to run CrypTool 2.
No admin rights are needed for the installation.
Each build is available as an .exe installer and as a compressed zip archive. Both have an online update mechanism. The .exe installer supports registration of start menu entry, desktop link and explorer file type, but does not support more than one .exe installation. If in doubt, use the .exe installer.
