Once ready to license the software, you may purchase a license online and activate your already-downloaded software instantly.

Important Notes

  • Python is distributed as a separate installer (required only for exporting publication-quality figures)
  • See Version History below for information on differences among releases

KinTek Explorer Version History

Starting with version 11.1.1, Python is distributed as a separate installer rather than bundled with KinTek Explorer. Python is only required for exporting publication-quality figures. Download the Python installer separately if you need this functionality.

All new users should download the latest version of the software. We release new versions often, and each release includes bug-fixes in addition to new features listed below.

Troubleshooting

See the KinTek Explorer Installation document above for general instructions. If your problem is not addressed there or below, please contact us.

v10 with Python bundled in MacOS Catalina: "KinTek_Explorer cannot be verified because the developer cannot be verified"

In some old versions of KinTek Explorer, you might see MacOS's security system flag the KinTek Explorer app as "untrusted". Due to bundling Python. To work around this problem, go to "System Preferences" -> "Security and Privacy" -> Go to tab "General" -> You should see a message about "KinTek Explorer", click "Open Anyway".

OSX: can't install from DMG - "no mountable filesystems"

This is a permissions issue sometimes encountered on OSX 10.11 (El Capitan). If you have this issue, try downloading the alternative version for 10.11 users. Double click the downloaded .tgz file to unzip it, and move the resulting application folder wherever you like. This is a zipped package, and as such is not "code-signed" by Apple, so you will be warned that it comes from an unknown developer. This is expected. A better solution, if possible, is to upgrade your operating system.

Menubar offset, mouse-clicks don't work unless you click under/above a button.

This is an OpenGL driver issue on your computer. We have seen this in particular on Windows laptops with Intel HD Graphics using drivers ending in .4664. The drivers found by Windows Update are not the most recent, and you must get the lateset drivers directly from Intel or the appropriate company. For Intel HD graphics, see this page.

Problems exporting publication-quality figures and graphs

This feature requires Python with matplotlib and numpy installed. Download the Python Installer above for the easiest setup, or ensure your existing Python installation includes these libraries.

How does KinTek Explorer find Python on my system?

Starting with version 2025.11.4, KinTek Explorer searches for Python in the following order:

  1. KinTek Python Distribution (Recommended) - Checks for the kintek-python installer in your home directory first. This is the most reliable option.
  2. System Python - Looks for Python in your system PATH. On macOS, the application also checks shell configuration files (~/.bash_profile, ~/.zshrc, etc.) to find Python installations like Anaconda or Homebrew Python that may not be in the GUI application's PATH.

Note for macOS users: If you use Anaconda, Homebrew Python, or other custom Python installations, make sure your shell configuration file (~/.bash_profile or ~/.zshrc) includes an export PATH= statement with your Python location. The application reads these files to locate Python when launched from Finder.

To verify Python is detected correctly, check the application's Python status indicator or export a test figure. Python must have matplotlib and numpy installed for figure export to work.
