Teensy 3.5 not showing up on Arduino IDE 1.8.9

[tomdouglas]

Hi, Folks!

First off, forgive me for not knowing how to use this forum..... Not sure my message got posted earlier.

Mostly, I updated the Arduino IDE from 1.8.7 to 1.8.9. Downloaded Teensy.exe and executed. Downloaded Teensyduino and ran that, all per the "Getting Started" page on pjrc website.

I can pull up the Board list on the IDE but no Teensy is listed. The Port option is grayed out although I can see that avrdude is attempting to connect through COM3.

The fast-blink compile output is attached. Before this, I used the IDE 1.8.7 and several months ago added Teensy 3.5 to it without a hitch.

What am I missing?

Thanks for your help!

Hi Tom - first message posted is the indication - glad you stopped back.

If TeensyDuino completed the install - but no Teensy boards show up then the running version is not where TeensyDuino installed - seems you have multiple copies of the IDE and TeensyDuino went on 'the other one'?

However looking at the attached TXT file it shows this:

Arduino: 1.8.9 (Windows Store 1.8.21.0) (Windows 10), Board: "Arduino Duemilanove or Diecimila, ATmega328P"

TeensyDuino can not install on the STORE copy - it has to be a copy installed from the Arduino 'Software - Downloads' page, but not the 'Windows App' - either download the ZIP and extract to a known directory - or download the installer version for the CURRENT 1.8.9 build { not an hourly or beta build }

If you only want to use Teensy then uninstall the Windows Store copy first. - Even if you do have other Arduino devices - it might be less confusing to uninstall that and just use a single copy installed as above.

It's interesting that the Windows Store version showed up.... I haven't used that version for a few years. I wonder if it didn't completely uninstall.

I took another shot at installing Teensy with success. I uninstalled what appeared to be two installs, and one could have been the Microsoft Store for all I know. Rebooted, installed the IDE, TeensyDuino, Teensy. That brought up Teensy's communications wide open.

Thanks a bunch for your help.
