Hi, I was using **Genie** (version **0.29.0** ) on **Julia 1.2** without issues, but i had to use use it on another computer (also Julia 1.2) and i can’t add it anymore.

```julia
(v1.2) pkg> add Genie

- I can’t use another version of Julia (it’s for a project which is in Julia 1.2)
- I tried to install the packages that have compatibility issues separately but I’m always blocked with Nettle.

```julia
(v1.2) pkg> status BinDeps
    Status `C:\Users\amoreaub\.julia\environments\v1.2\Project.toml`
  [9e28174c] BinDeps v1.0.1

(v1.2) pkg> add Nettle

Do you guys have any advice for me ?

Thx for your help.
