Installations in AFS and CVMFS

Standalone installations with minimal external dependencies are available at:



Versions for many different platforms and compilers are available at: /afs/

To use ROOT directly from AFS:

. /afs/
. /afs/

Direct Git repository access

The entire ROOT source can be obtained from our public Git repository:

git clone

The release specific tag can be obtained using:

cd root
git tag -l
git checkout -b v5-34-34 v5-34-34


Windows 7/Vista/XP/NT/2000 are supported. We offer two packaging types:

  • exe: a regular Windows installer package also setting up the required environment variables. With uninstall via "Control Panel" / "Add or Remove Programs". Simply download and start, or open directly. You can double-click ROOT to start it, ROOT files get registered with Windows.
  • tar: the traditional variant. Unpack e.g. with 7zip. Start ROOT in a Microsoft Visual Studio Prompt (in Start / Programs / Microsoft Visual Studio / Tools). If you installed ROOT to C:\root then call C:\root\bin\thisroot.bat before using ROOT to set up required environment variables.

Important installation notes

  • You must download the binary built with the exact same version of Visual Studio than the one installed on your system.
  • Do not untar in a directory with a name containing blank characters.
  • Take the release version if performance matters.
  • If you want to debug your code you need the ROOT debug build (you cannot mix release / debug builds due to a Microsoft restriction).
