VAPOR Windows Binary Installation

To install VAPOR on Windows 7 or Windows 8:

  1. If you are using antivirus software, you should disable it during the installation, as it may interfere with the execution of some scripts that are run during the install.
  2. If you have previously installed VAPOR (version 1.1.0 or later*), uninstall it as follows:
    1. From the start menu click settings->Control Panel, to launch the Control Panel, and double-click "Add or Remove Programs".
    2. Select VAPOR and click "Remove", and follow the instructions to remove VAPOR from your computer
  3. Download the file vapor-x.x.x-win64.msi where ‘x.x.x’ is the version number.  (or download vapor-x.x.x-win32.msi to install 32-bit VAPOR).
  4. Double-click on the downloaded .msi file to begin the installation.  The default installation will install VAPOR in the Program Files directory. 

You can launch the VAPOR user interface or VDCWizard by double-clicking on the appropriate icon on your Programs menu.  If you double-click on a VAPOR session file (*.vss) or on a VAPOR metadata file (*.vdf), this will launch the VAPOR GUI user interface, and initialize it with the specified file.  On some Windows systems you may need to associate .vdf and .vss files with vaporgui.exe . You can also launch the VAPOR GUI user interface, VDCWizard, and the other VAPOR executables (raw2vdf, vdf2raw, vdfcreate, wrfvdfcreate, wrf2vdf, ncdf2vdf,etc, ) by typing the command into a windows (DOS) command shell that has been initialized according to the instructions below.  If you have IDL installed on your system, you are already set up for using the VAPOR IDL library.

Pre-compiled binaries are built with compiler optimization enabled, and IDL support turned on. Sites requiring a different configuration will need to build VAPOR from source code.

User Environment Setup

The Windows installer will put VAPOR's executable files in

C:\Program Files\NCAR\VAPOR\bin

by default.  If you would like to run these executables from any directory on your computer, you can run the command

vapor-setup

in a Windows command shell (DOS shell), which will add the VAPOR executables directory to your system PATH in that DOS session.

CYGWIN users may issue the following commands (BASH or C-SHELL) to utilize VAPOR's applications from any directory in their current terminal [Note:  You must place the quotation marks (") as indicated here!] :

from C-SHELL:
source "$VAPOR_HOME/bin/vapor-setup.csh" 

from BASH:
. "$VAPOR_HOME/bin/vapor-setup.sh"
