I am running it on wsl in windows , I have checked the missing file is present

Looks like you're missing libnss3-dev. Try this:

sudo apt-get install libnss3-dev

[ShaleenAg]

Tried it but it didn't work . libnss3 was installed without any problems , here's the output

/destreamer.sh -u **user** -i https://web.microsoftstream.com/video/5adacbb0-3c52-45dc-9e46-c7a46b118df8

it's asking for libcups or something, I have tried searching for it but couldn't figure out the package needed

[lukaarma]

This should be the right package to install sudo apt-get install libcups2 (source here)

I assumed you were using the latest ubuntu distro, let me know if that's not the case (not that matters much I think)

[ShaleenAg]

I solved that and there were some other packgaes missing too which I had to install but when i launch it from my wsl it opens the chrome window in wsl but it crashes every time when loading the Microsoft login page Is there anyway I could execute it in windows without using a VM?

[lukaarma]

You can install node and ffmpeg in windows and run it there without any problem

[ShaleenAg]

I tried running on windows but it threw this error

ENOENT means No such file or directory. Try running npm install again after removing node_modules altogether and move destreamer-master to root of C drive so the overall path to Chromium becomes shorter. It's a Windows thing (255 chars in path max).

You can also do this:

 subst Y: C:\Example\File\Path\to\destreamer-master

Then switch to Y: and give it a go.

Thank You, running npm install after removing node_modules worked
