	I can no longer seem to upload from Visual Micro. Arduino IDE works fine. I've tried the "rescan", I've tried reloading the extension. Google talks about this error in the context of python tools, but I don't believe those are loaded. There was one message about a similar error in this forum from 3 years ago, but it didn't help.

	We need to see the visual micro error. Also please switch on vmicro>compiler>verbose, then try the upload then post the output as a .txt file. Thanks

I will capture verbose output later today (not in front of that PC at the moment). Here is the error in text format: Uploading 'NodeMCU_Breathing_Test' to 'NodeMCU 1.0 (ESP-12E Module)' using 'COM4' The uploader returned an error error: unknown board: nodemcu known boards are: none ck wifio warning: espcomm_sync failed error: espcomm_open failed

	Yes thanks. The verbose output will show useful info

	Okay... I found the issue, and a work around. I remoted into that system (but the ESP isn't connected.) Apparently, there were too versions of esptool.exe in two subfolders under appdata. So, I made the error go away by copying the esptool 0.4.9 to the 0.4.5 folder. But: How does Visual Micro decide which one to use? (Arduino IDE found the right one.) Is it safe to simply delete the old folder? Code Uploading 'NodeMCU_Breathing_Test' to 'NodeMCU 1.0 (ESP-12E Module)' using 'COM4' Uploader started for board NodeMCU 1.0 (ESP-12E Module) Upload method will be: bootloader Uploading via Bootloader l.exe -vv -cd nodemcu -cb 115200 -cp "COM4" -ca 0x00000 -cf C:\Users\bph\AppData\Local\Temp\VMBuilds\NODEMC~1\ESP826~1\Debug/NODEMC~1.BIN The uploader returned an error (Don't get me wrong, the price for Visual Micro is a pittance compared to the ability to use a real development environment. But this was frustrating last night, for sure.) Thanks.

	Thanks for the info. It's possible you have a partial install of a different esp tool chain. The board manager system didn't used to clear tool chains fully. I guess the arduino ide is doing a better job at ignoring it. I suggest you delete C:\Users\bph\AppData\Local\arduino15\packages\esp8266 folder. Then restart the ide and use board manager to install the latest esp tool chain. That way you will have a clean setup

	That seems to have cleared it up. I'll play more with the debugging tonight. Tim@Visual Micro wrote on Mar 9^th, 2017 at 7:21pm: Thanks for the info.
