I’m running Juno for JuliaPro 0.5.1.1 on Windows 7 with boost C++ library installed. I’m getting this message when I run the first program from IDE, but the program seems to run fine:

As a workaround you can disable the powershell wrapper that handles interrupts via `Settings > Packages > julia-client > Enable Powershell Wrapper`.
I’m not sure why you’re getting that error, but then I don’t have any idea what the prebuild boost installer does… Can you check `PATH` for anything suspicious? In particular, does `C:\boost\stage\lib` exist and is it on your `PATH`? Removing it might fix the error as well.

‘C:\boost\stage\lib’ specified in ‘LIB environment variable’ didn’t exist, so I deleted LIB. The question is: what Juno was looking for inside LIB?

It wasn’t – the powershell wrapper needs to import some kernel functions from `Kernel32.dll` and `DllImport` apparently tries to look at `PATH` or `LIB` while doing that or something. Not sure if we could work around that somehow…

No problem, I just needed to clean up my Windows environment variables. Thank you for pointing me in the right direction.
