Hello  
I start with Legato and Sierra Wireless IDE Developer Studio.  
For the moment, I am trying to program the FX-30 with a basic application “Hello World” by following a tutorial “FSEgate of April 2017”.  
When I “Build and install app”, I get an error message:

"HelloWorld Run  
Execute 3 tasks  
Connecting to device  
Target is already connected  
HelloWorld Build  
Project contains error  
Install HelloWorld  
Can not find binary artifact for HelloWorld  
Can not find binary artifact for HelloWorld  
"  
I’m looking for but I do not really understand.

Can someone help me ? thank you so much

To clarify, I think the problem comes from “Docker problem”.  
When I go to Windows\> Preferences\> Docker, I have this warning:  
“The ‘docker-compose’ command could not be located in C: \ Users \ Valentin \ VirtualBox VMs \ legato-docker-vm”

Hi @valentin_pl  
we recently noticed that Developer Studio on Windows is not compatible with VirtualBox 6  
You need to install VirtualBox 5 instead ([https://www.virtualbox.org/wiki/Download\_Old\_Builds\_5\_2](https://www.virtualbox.org/wiki/Download_Old_Builds_5_2)) to get it back to work.

" Cannot find binary artifact for mangOH"
