In order to proceed with offline installation, the license pack and the data packs need be downloaded separately in a machine which has internet connectivity and then copied over to the install machine so that the Install Manager can access them at install time. ## Recommended Installation Steps 1. Download License pack on a machine with internet access using the License Key 2. Download datapacks (`*.lfz` files) on a machine with internet access 3. Copy the downloaded license pack and downloaded datapacks to the machine where they have to be installed (with no internet access) 4. Run the Install Manager on the install machine to install the datapacks The following sections demonstrate the steps in the data installation process. ## Graphical User Interface Mode ### Download Install Manager should be run on a machine which can access the internet. If a proxy server is used, the checkbox "Use Proxy Server" needs to be checked and the Proxy server name and port need to be entered as shown below. If the proxy server needs authentication, the checkbox "Use authentication for proxy server" should also be checked and the user name and password need to be provided. The first step is to provide the installation folder. The Loqate License Pack will be written to this folder. Until 2015Q1 release, the Loqate license pack was named `loqateLicense`. From 2015Q1 release the license pack format is changed from `loqateLicense` to `license.lfs`. In the next step provide a license key. When a license key is entered, Install Manager will communicate with `licensing.loqate.com`. If the license key is valid, the server will return the corresponding license pack to Install Manager and then Install Manager will write the license pack to the installation folder. Once the license pack is saved to disk, Install Manager will display the contents of the license for reference. There are 2 options available for downloading as shown below. Select the "Download datapacks" option to download the required datapacks. After a valid option is selected, Install Manager will communicate with `licensing.loqate.com` and fetch details about the latest available licensed data packs that are compatible with the Local API version that is currently installed. The details of available data packs to install will be shown next. In the case a user selects an existing data folder for installation, it will show newer data packs available to download and install. The release date of the available data packs will also be displayed. The user can select the required data packs from this screen by checking the checkboxes next to each product. If the user selects the download option, Install Manager will download the data packs. The download can be paused and resumed at any point. If the "Pause Download" button is pressed the UI will change as follows: The next screen displays location where the downloaded data packs will be installed. Since the datapacks are to be installed on a different machine, the installation can be stopped at this stage by closing the window or by the 'Cancel' button. ### Installation Once the downloaded license pack and datapacks are copied to the Install machine, run the Install Manager on the install machine. Select the installation folder, the license pack can be placed in this folder. Choose the option "I have a license pack" and select the license pack file. From 2015Q1 release onwards, if the older format license pack `loqateLicense` is selected, it will be changed to the new format `license.lfs` Install Manager will display the contents of the license for reference. In the next screen choose the option "use local data packs" and select the folder where the downloaded datapacks were copied to. The available datapacks will be displayed for selection. Once the required datapacks are selected for installation, continue by clicking 'Next' button. The next screen displays location where the downloaded data packs will be installed. Next, the user is shown the data license agreement. Once the user accepts the license agreement, the next screen will proceed to installing the selected data packs. Finally, Install Manager will complete the installation as shown. The install folder will now have the `*.lfs` files along with `*_manifest.properties` for the datapacks which were selected for installation. ## Command Line Interface Mode Install Manager can be started in command line mode by providing the command line option: `mode=commandline`. Command line mode is the default in Linux and UNIX platforms. On Linux/Unix platforms, Install Manager can be launched by running the script `InstallManager.sh`. ### Download The first screen displays the version of the Local API currently installed. If a proxy server is used, the Proxy server name and port need to be entered as shown below. If the proxy server needs authentication, the user name and password need to be provided. The first step is to provide the installation folder. If the user selects an empty folder the installation will proceed as a fresh installation of the data packs. If the user selects an existing data folder, the installer will proceed as an update installation. The next step is to provide a license key. When a license key is entered, Install Manager will communicate with `licensing.loqate.com`. If the license key is valid, the server will return the corresponding license pack to Install Manager and then Install Manager will write the license pack to the installation folder. Choose the option to download the datapacks. When the list of available data packs is shown, enter `all` to select all data packs. Alternatively, if only certain products are desired for installation, enter the numbers next to those products, ending the selection by entering `done`. Install Manager downloads data packs from `download.loqate.com`. ### Installation Once the downloaded license pack and datapacks are copied to the Install machine, run the Install Manager on the install machine. Select the installation folder, the license pack can be placed in this folder. Choose the option "I have a license pack" and select the license pack file. From 2015Q1 release onwards, if the older format license pack `loqateLicense` is selected, it will be changed to the new format `license.lfs`. Install Manager will display the contents of the license for reference. Choose the option "install using locally available data packs" and select the folder where the downloaded datapacks were copied to. The available datapacks will be displayed for selection. Next, the user is shown the data license agreement. Once the user accepts the license agreement, the Install Manager will proceed to installing the selected data packs.
