I suspect you are running into troubles because your user path contains accented caracters but you will have to wait for a Windows user to chime in on what to do. ---

Maybe it is the accented character, but it could be something else. In the interest of time, just try the nuclear option … _First_, run `Windows PowerShell`. Then: 1. Inside PowerShell run the following command: 2. Wait for a couple seconds 3. Go back to step 1! You will do it five (5) more times. _Second_, run `File Explorer` and delete the following directories if they exist: - `C:\Users\Elève\AppData\Local\Programs\DiskuvOCaml` - `C:\Users\Elève\AppData\Local\Programs\DkMLNative` - `C:\Users\Elève\AppData\Local\Programs\DkMLByte` _Third_, download and run the newer “preview” 2.0.2 Native installer at [https://gitlab.com/diskuv-ocaml/distributions/dkml/-/releases/2.0.2/downloads/setup64nu.exe](https://gitlab.com/diskuv-ocaml/distributions/dkml/-/releases/2.0.2/downloads/setup64nu.exe) _Finally_, if it still doesn’t work, schedule an appointment with me at _contact me with a private message_ ---

Sorry but it didn’t work either… Can we organize a visio call to resolve the problem (I will soon be an informatic engineer student and I really want to master the basics of the language before classe starts ! PS: I’m french
