I second it. It fails during VS.Code launch with the same permission denied. :( Few weeks ago everything was ok( for more than 1 year).

Here is mine:

[ivankravets]

Do you have antivirus tools in a system?

[krukhlis]

Yes, I do. I have Avast. But I have already tried to disable my AV and restart VS.Code -- it fails once again with the same issue. :( And what is surprising me -- VS.Code version is the same as it used to be, Python is the same as it used to be. But somehow my lovely Platform.IO is crashing now. :(

[ivankravets]

1. Stop Avast
2. Remove C:\Users\krame\.platformio\penv folder
3. Restart VSCode.

[krukhlis]

I've tried to follow your recommendation. The problem is it will allow me to remove everything from .platformio, beside c:\Users\KRU\.platformio\penv\Scripts
When I try to remove it -- Windows says permission denied. Wtf, this is the folder of my Windows user under my Windows user home. And my Windows user is local admin.
I've tried to remove it from CMD running as Admin, but total fail:

[ivankravets]

Avast blocked it. Try to restart machine and remove this folder.

[krukhlis]

Oh, yes! After reinstall I had to disable Avast before any re-attempts to remove the folder. After that removal was successful. And when I started VS.Code -- PlatformIO was successfuly installed. The only problem is all my platforms, boards and libraries are gone now. I need to download them once again. :(

Sorry for this :( You need only remove ~/.platformio/pevn folder, not whole .platformio. In any case, you no need to worry when you remove .platformio folder. All declarations should be done in platformio.ini using platform and lib_deps options. In this case, you will have 100% reproducible working environment on any machine.

[krukhlis]

Offtopic: Wow, Either I've missed it before, but it looks like you have added "Devices" page, where one can see all available COM-ports and their usage!!! That's definetly highly demanded feature -- otherwise you need to go to Device manager and check it by yourself. Thanks guys. Awesome!

[ivankravets]

but it looks like you have added "Devices" page,

Do you mean PIO Home > Devices?

[krukhlis]

Yeh, exactly. Few months ago( maybe 4-6 months) I was asking for such functionality. But people were complaining it's hard to implement because of the different nature/interface API of com ports under different operational systems. Which is confusing to me -- because even in ugly Arduino IDE this is available almost starting from first version.

Where did you ask that? This feature was added to PlatformIO 5 years ago :)

[krukhlis]

This feature was added to PlatformIO 5 years ago :)

Either it was not visible in Win 7 PlatformIO for VS.Code, either I finally need to go to optometrist for glasses( :) ). Anyway, that's exactly what I was waiting as part of essential features upgrades. And now I can enjoy it.

@ivankravets Thanks for your prompt help with this issue. The only thing that concerns me now is why Avast has decided suddenly to ban PlatformIO installer/python, etc -- they co-exist on my machine for a long time. And the author of this issue(@Denkra ) has faced it today as well( I don't even know if he has the same Avast/Antivirus root cause). Weird. :(

[ivankravets]

PlatformIO is a fully open source and is written in Python. VSCode just wraps PlatformIO Core (CLI) and call platformio.exe which is actually a Python script. Avast and some other strange antivirus tools think that we are a virus and do something bad. You can actually exclude ~/.platformio folder from AVast and it should work.

So, the final scheme looks like: VSCode > Node.JS > Python > PlatformIO Core sources.
