The simplest Teensy 3.6 program that previously compiled using Arduino-1.8.5 and Teensyduino 1.40 (downloaded 2 weeks ago) on a Windows 10 64-bit system, no longer compiles. It takes nearly 30 seconds to reach the error below, and the Teensy Loader window never appears:
I exited the IDE completely, and tried running the Arduino IDE as an administrator, but no luck. I tried previous versions of the IDE, but no luck.
I temporarily turned off the McAfee LiveSafe real-time scanner, and this worked! Running the IDE with admin rights was not required.
Turning the real-time scanner back ON and adding C:\Programs\arduino-1.8.5\arduino.exe to the McAfee real-time scan exclusion list was not enough to solve the problem. This list must also include arduino_debug.exe and arduino-builder.exe.
Hopefully future versions of the IDE and/or Teensyduino will solve this problem.
Code:
