INSTALLING CAPTURE

Capture is available for Windows and macOS. The Windows version of Capture is compatible with Windows 8.1 or newer, including Windows 10 and Windows 11. The macOS version of Capture requires macOS 10.14 (Mojave) or newer.

Durridge offers older versions of Capture for versions of Windows dating back to Windows XP, and for macOS systems dating back to Mac OS X 10.6. These versions of Capture may be downloaded from the Legacy Versions of Capture page at the Durridge website.

To run Capture, a computer must have at least 4 GB of memory. A display resolution of 1280 by 800 pixels is required, but a full HD display (1920 by 1080 pixels) is recommended for viewing radon data graphs in high detail. HiDPI/Retina displays are fully supported.

Capture can communicate with the RAD8 via the USB-A to USB-Mini B cable supplied with the RAD8. It can communicate with a RAD7 using the serial to USB adaptor included with the RAD7. In either case it may be necessary to install driver software. The appropriate driver installers are available at the Software Drivers page on the Durridge website.

To install Capture on Windows, download the Capture application installer from the Durridge website. Launch the installer and follow the on-screen instructions.

The installer will place shortcuts to the application on the Windows desktop and in the Start Menu if desired. The installer will offer to launch Capture 8 when the installation is complete.

Bypassing Microsoft Defender SmartScreen

Note that when launching the Capture installer or the Capture application for Windows for the first time, you may see a warning from Microsoft stating that "Windows protected your PC. Microsoft Defender SmartScreen prevented an unrecognized app from running". If this happens, click "More info" as shown in Figure 3 below.

Next check the App and Publisher information as shown in Figure 4 below, and if it is correct click Run anyway:

Microsoft Windows SmartScreen may flag newly released software as potentially hazardous, even if the application contains a digital signature from a reputable developer. Be assured that Durridge software has been code-signed by the manufacturer and will not put your PC at risk.

To install Capture on macOS, download the Capture disk image from the Durride website, and mount it on your computer's desktop. Open the disk image, and drag the Capture application icon onto the nearby alias of the Applications folder to copy it to your computer. Locate Capture in the Applications folder and drag it to the Dock for easy access if desired. Unmount the Capture disk image after the application has been copied to your computer.

It may be necessary to adjust the system's Security settings to allow Capture to launch. In the System Settings, enter the Privacy & Security panel and make sure that the system is set to allow applications from identified developers, rather than being restricted to applications downloaded from the App Store. It may also be necessary to right-click on the Capture application and choose Open from the pop-up menu that appears, to bypass security restrictions.

Capture 8 is offered in two editions: Capture 8 Pro and Capture 8 Lite. The Lite edition is provided free of charge, and it includes the features found in earlier Capture releases, in addition to basic support for the RAD8. Capture Pro offers a host of advanced features, unlocking the full potential of the RAD8. Capture Pro also provides access to Capture Cloud, Event-Driven Actions, and other advanced program functionality.

To purchase a Capture Pro license, visit https://durridge.com/software/capture/.

After purchasing a Capture Pro license, you will receive a License Key from Durridge. To activate Capture Pro, launch Capture 8 and choose Capture License... from the Help Menu (on Windows) or the Application Menu (on macOS). Enter your name, email address, and License Key in the Capture License Window as shown in Figure 6, below. A Capture Pro License Key consists of five sets of four alphanumeric characters, separated by dashes.

If you would like to try Capture Pro before committing to the purchase of a license, choose "I want to start a 30 Day Capture Pro Trial". After the trial period ends, Capture will revert to Capture Lite.

If you have purchased Capture Pro but you do not know your License Key, or if your License Key has been lost, click I don't know my License Key. This will connect to a form on the Durridge website, which you can submit to obtain your License Key.

If you are running Capture on a computer that can not be connected to the Internet, it will not be possible to activate Capture 8 Pro by entering a License Key. Instead you can activate the software by loading a Capture 8 Pro License file from disk. To obtain a License in this format, contact Durridge about the situation, and we will send a License file as an email attachment. After receiving the email, copy the attached License file to a USB stick, and transfer the file to the computer running Capture. Then in the Capture License Window, click Load License from file. A dialog box will appear, prompting you to select the file. Choosing the License file will activate Capture Pro.
