Windows Nim first time user experience with choosenim, dlls.zip download,extract problem.
With choosenim presenting itself as the easy way to get Nim, it currently gives a bad first experience for Nim on Windows.

Following the instructions: 

Going to the releases page (not seeing the note about getting the zip) and getting the exe instead expecting it to be an installer.
Attempting to run the downloaded exe, nothing appears to happen.

Reread the instructions and see the note about needing the .zip. Get that.
Run runme.bat

```
$ ./runme.bat

            Now you must ensure that the Nimble bin dir is in your PATH:
              C:\Users\user\.nimble\bin
Press any key to continue . . .
```

run `choosenim stable`

```
$ choosenim stable

     Error: Unable to extract. Error was 'Cannot create a file when that file already exists.

```

Deleting the dlls.zip and running `choosenim stable`

```
$ rm ~/.choosenim/downloads/dlls.zip

Seems to be stuck in a loop that I can't do anything about.
I worked around this by using scoop install method instead, but I think the choosenim windows experience could be improved to make people's first experience of nim a more pleasurable one by making the exe be an installer, or get rid of it if the zip is required and obviously a fix for this dlls bug which seems unrecoverable at the moment.
