Hi all,

I am very new to Julia as well as to Discourse. I am trying to set up an environment to learn the language.  
I just downloaded the V1.5.4 binary from [julialang.org](http://julialang.org) and installed it as a user (not admin).

1. I lauched the REPL

2. Switched to pkg mode

3. Typed **update**

The stack error I got is below. I am not sure what I did wrong or if there are some steps I should do ahead of this.

Any clue would be appreciated.

```julia

(@v1.5) pkg> update

Could possibly be a corrupt registry. Have you checked to see if the file `C:\\Users\\Karl.KARL-M93P\\.julia\\registries\\General\\Registry.toml` does in fact exist? If not, you could try deleting the `General` directory and try to update again.

Thanks alot. That did it and the update completed correctly.

I did an uninstall of julia earlier this morning while chasing this problem but I suppose  
the .julia directory was not removed.

Great. Welcome to Julia land 😁
