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. You can double-click ROOT to run it; ROOT files get registered with Windows. + * **tar**: unpack e.g. with [7zip](https://www.7-zip.org). 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. Call instead `thisroot.ps1` if you run from a `powershell` (the default terminal in Visual Studio Code). + +### Important installation notes + + * You must download the binary built with the exact same version of Visual Studio (and Python) than the one installed on your system. + * Don't forget to select the component “Desktop development with C++" when running the Visual Studio Installer. + * 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).
