I have two versions of Julia installed on my machine `1.6.3` and `1.8.0-beta 1`. When I write `julia` in the PowerShell, it opens `1.6.3`, how can I select the demanded version? I tried something like below, but it didn’t work
```julia
C:\> julia-1.8.0-beta1
```

You can call the binary for the different installations by using the full path.
julia alone opens the binary that is available using the PATH environment variable.
I usually setup a custom shell in the new [windows](https://en.wikipedia.org/wiki/Windows_Terminal) terminal to start a specific version.

Thank you very much.
Another issue, I have many packages installed in `1.6.3` how can I made them installed also in `1.8.0-beta 1`, such coping some files…

I usually place a `Project.toml` or even manifest file in my project directories.
To generate them just activate the project directory in the package mode and then add the required packages. I think julia can then also use already installed packed without reinstalling.
In case you already have a `Project.toml` you can call instantiate in the pkg mode of the REPL to force an installation.
I usually only have very few packages installed in the default environment.
If you don’t want to use Project files you can also activate named environments by using `pkg> activate @myname`. I don’t know if they are available between version though.

The packages for the default environment are also stored in a Project.toml file.
You can find it by calling status
```julia
(@v1.7) pkg> st
Status `~/.julia/environments/v1.7/Project.toml`
[6e4b80f9] BenchmarkTools v1.3.1
[c3e4b0f8] Pluto v0.18.1
[b8865327] UnicodePlots v2.9.0
```

You can also use `juliaup` for this scenario, see [Julia in the Windows Store | David Anthoff | JuliaCon2021 - YouTube](https://youtu.be/rFlbjWC6zYA). Just make sure you uninstall your other Julia versions before you switch over to using `juliaup`.

I am not sure if it is possible, but can the Windows store version also ship with custom profiles for the Windows terminal? 😃

I’m also new to Julia, but here is what I do and I think they’re working well (I’m using MacOS):
Download and installing two versions of Julia, let’s say 1.6.7 and 1.9.3. Then add Julia to PATH by running:
```bash
sudo mkdir -p /usr/local/bin
sudo rm -f /usr/local/bin/julia1.6
sudo ln -s /Applications/Julia-1.6.app/Contents/Resources/julia/bin/julia /usr/local/bin/julia1.6
sudo rm -f /usr/local/bin/julia1.9
sudo ln -s /Applications/Julia-1.9.app/Contents/Resources/julia/bin/julia /usr/local/bin/julia1.9
```
And then I can launch different Julia by running `julia1.6` or `julia1.9` from terminal.
I think things will be similar in Windows or Linux. Hope it helps.

I would say this is not the preferred solution. Having `juliaup` installed makes managing versions very easy.
Add new channels (Julia versions) with `juliaup add 1.6.3` say and run with `julia +1.6.3`.
(The 1.6.3 is just an example, you can do it with `lts`, `release`, `beta` or specific julia versions)
You can then alias in your command line for the specific versions.

Thanks, I will have a try!

Would you mind pointing me to the documentation for the `+` option? I couldn’t find it on the [CLI page](https://docs.julialang.org/en/v1/manual/command-line-interface/#command-line-interface).
