Thanks for the report.

Can you show a screenshot of what you are trying to save when configuring the Arduino 2 Locations (before you click OK)?

Once set please attach a full build output as a text file with the below options enabled:

• vMicro > Compiler > Verbose
• vMicro > Compiler > Show Build Properties

When using the Arduino2 Configuration in Visual Micro, the board and library locations should be automatically detected, so there should be no need to set them on the IDE Location screen.

Since I can't get screenshots of vmicro drop down here is  the vMicro line. Also User Installed and builtin libraries are empty.
Was able to add ESP8266 but this is Heltec ESP32??
If I uninstall vmicro, what folders should I manually delete before I reinstall.
Here's the results of a Build & Upload the works in Arduino.
