CounterMeasure is a GUI application supporting XIA's UltraLo-1800 alpha counter.
.NET 4.5 (v1.1.32 and later): Installation of CounterMeasure v1.1.32 and later requires an update of Microsoft .NET Framework. This update is performed automatically by the CounterMeasure installer if your computer is connected to the Web. If your UltraLo laptop is offline, use another computer to download Microsoft .NET Framework 4.5.1 Offline Installer and install it on the laptop prior to installing CounterMeasure.
Driver installation updates (v1.1.38 and later): Due to updated security standards related to the verification of driver installation packages, installation of CounterMeasure v1.1.38 and later requires Windows 7 security update KB3033929. This update is installed automatically via Windows Updates. It can also be downloaded directly from Microsoft.
Windows 10 may display a warning "Windows protected your PC: Windows Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk." XIA tests and cryptographically signs all installers prior to release, so this warning may be ignored. Click "More Info", followed by "Run anyway". The installation will request User Account Control and proceed normally from there. If Windows reports a problem with the digital signature, stop installing and contact XIA support.
