If you are using a version of Spike2 before version 7 you should read this post about updating your USB device driver. Version 7 users will get the latest driver by updating to version 7.06 or later. Version 8 users have the latest driver (but read the next section about Windows 10).
64-bit Windows 10 and 1401 drivers
64-bit versions of Windows 10 will not register new drivers unless they have been signed for that version of Windows 10. Once registered, the driver is accepted; it does not require resigning if the operating system is updated to a newer release of Windows 10. We sign our drivers for each Windows 10 release and the installer code issues a warning if you install onto a newer version of Windows. This warning is not a problem unless this Windows 10 system has never seen a 1401 driver before.
Windows 11 accepts the latest Windows 10 signature (in April 2022).
If you install an old Spike2 (or Signal) release on a new Windows 11 or 10 system, you can get the most recent 1401 drivers by downloading and running the latest 1401 Windows installer.
Windows 10 version 1709, 1903, 1909 and Spike2 toolbars display bug
Windows 10 version 1709, also known as the 2017 Fall Creators Update, Introduced a display bug: when you drag a Spike2 (or Signal) toolbar, the drag leaves a mess behind on the screen that persists until the end of the drag. This affects other programs; it is not just a CED problem. We reported this (with some example code to generate the problem). It was fixed in the 2018 April Windows Update, version 1803. It was back again in version 1903. In 1909 it appears to be a problem if you have multiple screens with different screen scaling. There is now a fix: KB4541335 for 1909. Getting the latest updates should fix it for you.
Update: Windows 10 20H1 (May 2020) and 20H2 (October 2020) work on the main screen; other monitors with different screen scales may not show the drag rectangle or show it displaced.
Spike2 support and development
The following gives the dates and revisions of the latest release of each version of Spike2. We actively develop the latest version, and support (that is fix bugs) in the latest major release and the previous major release. We may choose to make changes to older versions for reasons of backwards and forwards compatibility. The current major release is 10, the previous is 9. There are links to the full revision history of each release, below.
Version 10.15c, July 2022
Version 10 is the latest major release of Spike2, first released in 2019 and is in active development. It runs on Windows 11, 10, 8 and 7. To sample data you need a Micro1401 mk II, a Micro1401-3 or a Micro1401-4 or a Power1401. You can sample data without a 1401 using a Talker interface. Version 10 adds Info windows, real-time filtering of 1401 data, user-defined objects in the script language and more. Version 10 is available in 64-bit and 32-bit builds.
Version 9.16, April 2022
Version 9 was originally released in 2017 and is no longer in active development. There are bug fix updates and occasional new features for reasons of compatibility with the latest version. It runs on Windows 11, 10, 8 and 7. To sample data you need a Micro1401 mk II, a Micro1401-3, a Micro1401-4 or a Power1401. You can also sample data without a 1401 using a Talker interface. Version 9 expands the number of channels in a data file, virtual channels, result view channels and XY view channels to 2000. Version 9 is available in 64-bit and 32-bit builds.

Version 7.20, October 2017
Version 7 was originally released in 2009 and is no longer supported. This is the last version that supports the 1401plus or the original micro1401 for sampling data.
