Windows (as Administrator)

Installation of HTCondor must be done by a user with administrator privileges. We have provided quickstart instructions below to walk you through a single-node HTCondor installation using the HTCondor Windows installer GUI.

For more information about the installation options, or how to use the installer in unattended batch mode, see the complete :doc:`../platform-specific/windows-installer` guide.

It is possible to manually install HTCondor on Windows, without the provided MSI program, but we strongly discourage this unless you have a specific need for this approach and have extensive HTCondor experience.

Quickstart Installation Instructions

To download the latest HTCondor Windows Installer:

  1. Go to the current channel download site.
  2. Click on the second-latest version. (The latest version should always be the under-development version and will only have daily builds.)
  3. Click on the release folder.
  4. Click on the file ending in .msi (usually the first one).

Start the installer by double clicking on the MSI file once it's downloaded. Then follow the directions below for each option.

If HTCondor is already installed.

If HTCondor has been previously installed, a dialog box will appear before the installation of HTCondor proceeds. The question asks if you wish to preserve your current HTCondor configuration files. Answer yes or no, as appropriate.

If you answer yes, your configuration files will not be changed, and you will proceed to the point where the new binaries will be installed.

If you answer no, then there will be a second question that asks if you want to use answers given during the previous installation as default answers.

STEP 1: License Agreement.
Agree to the HTCondor license agreement.
STEP 2: HTCondor Pool Configuration.
Choose the option to create a new pool and enter a name.
STEP 3: This Machine's Roles.
Check the "submit jobs" box. From the list of execution options, choose "always run jobs".
STEP 4: The Account Domain.
Skip this entry.
STEP 5: E-mail Settings.
Specify the desired email address(es), if any.
STEP 6: Java Settings.
If this entry is already set, accept it. Otherwise, skip it.
STEP 7: Access Permission Settings.
Accept the default values. You can change these later by modifying the configuration files.
STEP 8: VM Universe Setting.
Disable the vm universe.
STEP 9: Choose Destination Folder

:index:`location of files<single: location of files; installation>`

Accept the default settings.

This should complete the installation process. The installer will have automatically started HTCondor in the background and you do not need to restart Windows for HTCondor to work.

Open a command prompt to follow the next set of instructions.

Setting Up a Whole Pool with Windows

Follow the instructions above through Step 1. Then, customize the installation as follows:

STEP 2: HTCondor Pool Configuration.
Create a new pool only on the machine you've chosen as their central manager. See the :doc:`admin-quick-start`. Otherwise, choose the option to join an existing pool and enter the name or IP address of the central manager.
STEP 3: This Machine's Roles.
Check the "submit jobs" box to select the submit role, or choose "always run jobs" to select the execute role.
STEP 4: The Account Domain.
Enter the same name on all submit-role machines. This helps ensure that a user can't get more resources by logging in to more than one machine.
STEP 5: E-mail Settings.
Specify the desired email address(es), if any.
STEP 6: Java Settings.

If this entry is already set, accept it. Otherwise, skip it.

Experienced users who know they want to use the java universe should instead enter the path to the Java executable on the machine, if it isn't already set, or they want to use a different one.

To disable use of the java universe, leave the field blank.

STEP 7: Access Permission Settings.

Machines within the HTCondor pool will need various types of access permission. The three categories of permission that can be set here are read, write, and administrator. The values can be usernames, hostnames or IP address ranges, Wild cards and macros are permitted. It is recommended that you accept the defaults here and change the values later as needed by modifying the HTCondor configuration files.

Read
Read access allows a machine to obtain information about HTCondor such as the status of machines in the pool and the job queues. If all of your HTCondor machines and users are in a single DNS domain or IP Address range, setting this to *.domain an IP address range with wildcards is a good choice. See ALLOW_READ :index:`ALLOW_READ`
Write
Write access is for submitting jobs to the Schedd. Setting this to * will allow any user that can login to the machine submit jobs. See ALLOW_WRITE :index:`ALLOW_WRITE`
Administrator
Administrator access is for starting and stopping the daemons and sending administrative commands such as reconfig and drain. By default the installer will give this permission to the Windows user that runs the installer and to the Windows Adminstrator account. See ALLOW_ADMINISTRATOR :index:`ALLOW_ADMINISTRATOR`

For more details on these access permissions, and others that can be manually changed in your configuration file, please see the section titled Setting Up Security in HTCondor in the :ref:`admin-manual/security:authorization` section.

STEP 8: VM Universe Setting.

Disable the vm universe.

Experienced users with VMWare and Perl already installed may enable the vm universe.

STEP 9: Choose Destination Folder

:index:`location of files<single: location of files; installation>`

Experienced users may change the default installation path (c:\Condor), but we don't recommend doing so. Certain jobs may not run if the installation path has a space in it.
