Yes sorry, I see that I was wrong but after that I run the correct command.
The results is nothing again
....do you think that is better to remove node-red completely and re-install?

_ **Not sure** _, I think the **npm prefix** is not correct, the following command should return you `C:\Users\Nu!Reha\AppData\Roaming\npm`:
```bash
npm prefix -g
```
If not, it can be set with the command
```bash
npm config set prefix C:\Users\Nu!Reha\AppData\Roaming\npm
```
Then
```bash
npm install -g --unsafe-perm node-red@latest
```

Please be specific. Show us exactly what you entered and what you seen.
And show us the startup log.

No, but worth a try at this point.

Great, it works!
`npm prefix -g` returns `C:\ProgramData\npmglobal` so I set the new path and now node-red is updated!
Thank you so much 😍

I see you have at some point changed npm global location - you should delete all node\_modules from the old location to avoid this sort of thing in the future..
i.e. if you are now using a machine global path (e.g. `C:\ProgramData\npmglobal`) instead of a user global path (e.g. `C:\Users\Nu!Reha\AppData\Roaming\npm\node_modules`) then get rid of `C:\Users\Nu!Reha\AppData\Roaming\npm\node_modules` completely.
PS: I use a machine path for global modules too (makes more sense)

I honestly don't know. I installed Node-Red a few years ago, can't remember when, and I just follow the official instructions for Windows.

In `environment variable` I have nothing about `npm` in `System variables - Path` (I don't know if this is the right name in english, I'm sorry) but `C:\Program Files\nodejs\`.
Instead, I have `C:\Users\Nu!Reha\AppData\Roaming\npm` in `User variables - path`.
What I have to change avoid this problem in future?

@coat
Sorry; I'm very late to the party.
Are you aware that there's a [Windows Installer for Node-RED](https://github.com/node-red/windows-installer/releases) available?
As we're still in (late) beta testing, I'd be very interested how this installer is handling your issue.
Could you please give it a try and report back the result?
Thank you in advance! Would be highly appreciated!

😉 You could as well just launch the installer and let it walk through the actions where it tries to analyze your system (without actually doing any installation) - to check if it is able to detect things properly.

Done.
It detects the newer version of NodeJs I installed yesterday e suggests to me to keep it.
Then it detects the newer version of Node-Red (3.0.2) e suggests to me to keep it and that the Global installation was in `C:\Users\Nu!Reha\AppData\Roaming\npm`
Finally....I tried to install 😅
At the end I start Node-Red and all my flows disappeared.
I think they are still here.....somewhere 🤣
Anyway I exported all before the installation and everything it's fine
