Cannot open source file "Particle.h"

Hello,

Brand new user here. I just installed VS Code and Particle Workbench and have immediately run into problems. I am getting the apparently common issue of not being able to find libraries. In my case it is the example sketch that opens with a new project, and it cannot find "Particle.h"

I made sure I configured my project for my device using the most recent firmware:

I have been following this guide: Intellisense: Report Issues Here

Here is a sanitized audit report:

And here is a screenshot of the environment, example sketch and all:

Reset the intellisense database and still nothing.

Any help would be appreciated.

Thank you

edit: I just tried uninstalling and reinstalling the local compiler toolchain. This reliably re-creates another issue I noticed during all of this:

Every time I would initially set my device, I received this same error.

I don't know for sure why you're unable to download the toolchain, but the problems could be related. Since the Particle.h file is part of the toolchain, if it wasn't actually downloaded before that would explain why Intellisense could not find the file.

However I think the underlying problem is that your Windows username contains a space, which has been known to cause problems:

Oh okay, interesting. I will try re-naming my PC, re-installing VS Code and the Workbench and report back.

Thank you, Rick! That was the issue.

Performed a clean install of windows and changed my username. The toolchains downloaded and now intellisense appears to be working.

I was looking for an excuse to de-bloat windows 11 anyways.
