Unable to set up dev environment in Windows 10

**Describe the bug**
I've tried several ways of setting up the project in Windows, without succeeding. The first attempt was to set up the environment as stated in the ```README.md``` by installing ```Windows build tools``` and ```node 12.18.3``` (as I need multiple node versions for different projects, I'm currently using [nvm-windows](https://github.com/coreybutler/nvm-windows). ```npm run bootstrap``` failed with the following error message:

```

Note: Running ```npm run bootstrap``` with admin rights also produces the same error message.

The second attempt was done by removing all ```package-lock.json```. This solved the issues during the installation but unfortunately, after running ```npm run app-start```, the Electron application loaded on a white screen with ```CANNOT GET renderer.html``` on it. Chrome Dev Tools didn't provide much information either and the console that was running the command complained about some library installed.

The last attempt has been to install it in the Windows Linux Subsystem, after downloading all the packages needed such as ```build-essential```, ```font-manager``` and so on. The error message has been an ```EINTEGRITY``` error.

I've also tried to install everything using yarn just for fun, also without succeeding.

**To Reproduce**
Steps to reproduce the behavior:
1. In Windows 10, clone the repository.
2. Run ```npm run bootstrap```.
4. See error.

**Expected behavior**
Installation succeeds without exiting.

**Desktop (please complete the following information):**
- OS: Windows 10 Home

**Additional context**
Let me know if you think I could try anything else to fix this issue, I don't have anything in mind I could try.

Thanks for your help!

Start with README.md and the npm run bootstrap entry point, then reproduce the Windows 10 failure involving lerna, flow-bin, and package installation. Compare the npm run app-start result and the reported renderer.html error across the attempted setups. Done means the documented Windows setup completes and the Electron application starts without the reported errors.
