OOPS! Spoke too soon:
Failed to install platform: teensy:avr.
Error: 13 INTERNAL: Cannot install tool teensy:email@example.com: moving extracted archive to destination dir: rename C:\Users\ptt1957\AppData\Local\Arduino15\tmp\package-3824465983\tools c:\Users\ptt1957\AppData\Local\Arduino15\packages\teensy\tools\teensy-compile\1.56.1: Access is denied.
Since I was running IDE 2.0 as administrator, I'm not sure where that came from...
No reply needed unless you know what's going on. I can always use the new teensyduino installer with my old 1.8.xx.
Sorry don't know that one. either
A couple of guesses:
1) The file already existed there and as such the file could not be renamed
2) directory permissions. I don't have a machine that is setup with lots of privileges setup... So not sure.
As for installing without Internet... Not sure.
I know that with Arduino 1.x, that some would install stand alone mode and have everything in a nice contained place that they could copy to another computer or thumb drive...
But so far it looks like they have not implemented that for IDE2:
