Installation Instructions

## Windows

• Download the ".msi" installer file and double click to open.
• On Windows 10, sometimes, Microsoft Edge does not let you download installers from unknown sources for security purposes (the warning comes up after the download finishes); you will need to select "Keep File" and follow prompts.
• If a security prompt comes up after opening the installer, click on "Run Anyway".
• Follow prompts for installation.

## Linux

• Linux users have a CaPTk AppImage available called CaPTk_${Version}.bin. • To run the AppImage, first open a terminal in the same directory as the .bin file. • You will want to make sure it is runnable as an executable with the following command: chmod +x CaPTk_${Version}.bin

• To install CaPTk to the current directory where the AppImage was downloaded, run the following command:
./CaPTk_${Version}.bin  • To specify a preferred directory to install CaPTk, run the following command: ./CaPTk_${Version}.bin --target {path_to_preferred_directory}

• Follow prompts to install.

## macOS

• Users will download the ".pkg" file from NITRC; double-click the file.
• If there is a window saying that this is an "unidentified developer", hit "OK" and then go to "System Preferences > Security and Privacy" and you need to click on "Open Anyway" beside the "CaPTk_\$version.pkg" (this will prompt for your password).
• Double click on the pkg file and click on "Open". This will guide you through the installation screen with licensing information.
• Before installation begins, you may be prompted for your password again.
• You will find CaPTk under your "Applications" folder and you can delete the disk image.
