Install  

The Gas HCA Tool is installed using your Windows Installer from a Windows
Installer package (.msi) file; installation of the Gas HCA Tool is
straightforward if you have previously installed software applications on your
Windows machine. The Gas HCA Tool installer writes files to various Windows
system directories, including:

• • • 
      Program files

• • • 
      Python directory for ArcGIS Desktop 

• • • 
      Python directory for ArcGIS Pro 

The Gas HCA Tool installer requires you to have read and write access to these directories at runtime.  

Instructions for installing the Gas HCA Tool are provided using Windows 10 Pro.  

1. To begin downloading the Gas HCA Tool installation process, double-click on
   the Gas HCA Tool setup program (GasHCA_1.x._Setup.msi) to open the Gas HCA
   Tool Setup Wizard. Press ‘Next’ to continue with installation.
   
2. You must review the license agreement and click the ‘I agree’ radio button. Then, select the ‘Next’ button to continue with the installation. Otherwise, select
   the ‘Cancel’ button to end the installation.  
   
3. Next, select your desired installation directory by clicking on the ‘Browse’ button
   and navigating to the destination path. If no selection is made, the tool will install in the Windows Program
   Files directory; C:\Program Files\G2-IS\Gas HCA. Click on the ‘Next’ button to continue the installation. 
   
4. The ‘Confirm Installation’ window appears, and you must select ‘Next’ to continue the installation; otherwise, select ‘Cancel’ to exit the installation and ‘back’ to view the
   previous screen.  
   

 

5. In a typical Widows setting download environment procedure, the system will
   prompt you with a message indicating changes for which the downloader
   requires access to system files. You must grant access for the installer to
   continue the install. After doing so, the installer will show a progress bar
   for your installation. At any time during this process, you can select the
   ‘Cancel’ button to end and exit out of the installation.
   
6. The command prompt window installs your dependent Python packages for the
   Gas HCA Tool. If this window does not exit prior to seeing the ‘Installation
   Complete’ window in Step 7, do not exit this window. The command prompt will
   run its cycle and close the window when all packages have been successfully
   installed.
   
7. Lastly, the installer will display an ‘Installation Complete’ window. This
   window confirms the successful installation of the Gas HCA Tool. Select the
   ‘Close’ button to exit out of the installer window alone. If the Step 6
   command prompt window is still running, do not exit out of this window.
   Simply let it run the installation process. The window will exit after
