I've just installed the Beta version of Teensyduino 1.41 with the Teensy 3.5. I'm using Win 7 and Rel. 1.8.5 of the Arduino IDE. It appears that the installation of the Teensyduino software was successful, as I can see them listed in the Boards section of the IDE. My problem is that there is no COM port list and that menu Option is greyed out. I am also getting this error message:
Archiving built core (caching) in: C:\Users\econjack\AppData\Local\Temp\arduino_cache_769301\core\core_teensy_avr_teensy35_usb_serial,speed_120,opt_o2std,keys_en-us_3e0515dfaad153553690f968527624f2.a
exec: "E:\\Arduino1.8.5\\hardware\\teensy/../tools/teensy_post_compile": file does not exist
Error compiling for board Teensy 3.5.
The IDE is installed on my E drive in a root directory named Arduino1.8.5. If I switch away from the Teensy and connect a Mega 2560 Pro Mini and select it from the Board menu option, the Port option allows me to select, compile, upload, and run a program. I've read a number of posts on this subject, but none seem to have made any difference.
