Note 1: Before downloading a binary version make sure your machine contains the right run-time environment. In most cases it is not possible to run a version compiled with, e.g., egcs on a platform where only gcc 2.95 is installed. In such cases you'll have to install ROOT from source. See the configurations used to build the binaries below.
Do not untar in a directory with a name containing blank characters.
set TEMP=c:\temp set HOME=c:\your top directory set TMPDIR=c:\temp set ROOTSYS=c:\root (the directory where you installed Root) set PATH=%PATH%;%ROOTSYS%\binNote valid for all Windows versions:
The win32 and win32gdk versions have been compiled under VisualC++7.NET. These versions may not run correctly under Windows95 or Windows98 (we do not support these obsolete versions anymore). To use these files with the old VisualC++6, you may have to download the following DLLs and store them in a directory accessible in your PATH:
Procedure to install the FREE Microsoft VisualC++
The files described above have been compiled with the commercial version of VC++7.1 under Windows/XP Professional. Installing ROOT with the FREE version
of VisualC++ has also been tested by Bertrand Bellenot.
See Bertrand's instructions to install this FREE version.

Some old Windows systems may also require:
To install, unzip and untar the file. For example:
$ gunzip root_v5.08.00.Linux.slc3.gcc3.2.3.tar.gz $ tar xvf root_v5.08.00.Linux.slc3.gcc3.2.3.tar
This will create the directory root. Before getting started read the file README/README. Remember, you can find the full documentation of the ROOT classes on this web site at the location Classes and Members. The distribution also contains all tutorials and a set of test programs.
