Something is worng with your project. Try to recreate it from scratch. Also Netos 7.4 is extreamly old. Please upgrade to Netos 7.5.2 with all the patches installed.

I appreciate the response, but I don’t think its a problem with my project. I was trying to build on Windows 10 when I ran into this error. I installed Digi ESP on Windows 7 this morning, and was able to build it.
