Hello everyone! I’m trying to install OCaml on Windows using diskuv installer, but the installer install everything in the C disk by default. As i don’t hav enough space in it, i wanted to know if it’s possible to install it on a different Disk like the (D disk) ? ---

You can use a different location by using the `--verbose --prefix D:\blahblah` command line option of the installer. That and other options are available with `--help`. If that isn’t working for you, file an issue at [https://github.com/diskuv/dkml-installer-ocaml/issues/new](https://github.com/diskuv/dkml-installer-ocaml/issues/new) ---

Where can i use this different location command line, because the installer (exe) runs directly without giving any chance to type anything. ---

We are having a communication difficulty. Can you categorize yourself into one of the following two categories? ### Category 1 You are familiar with the terms “change directory” and “directory listing”. The following makes sense to you: - Run the Command Prompt, PowerShell or Windows Terminal to get a command line. - Change directory (`cd`) to your browser’s download folder - Do a directory listing (`dir`) to find the specific filename you downloaded - Run `setup-X.Y.Z.exe --verbose --prefix D:\blahblah` from that directory, replacing `setup-X.Y.Z.exe` with the specific filename you found in the last step, and `D:\blahblah` with a suitable directory on your D drive ### Category 2 You are _not_ familiar with the terms “change directory” and “directory listing”. That’s fine! Since day-to-day use of OCaml requires familiarity with those terms (more generally, the “command line”), you should pause briefly and find some material before completing the installation. I don’t know the best material for that though, so please respond if you are in Category 2 and perhaps one of the professors or teachers on this discuss forum can point you to material they use with their students. ---

Thank you so much for your detailed response! I ran the command setup-diskuv-ocaml-windows\_x86\_64-1.2.0 --verbose --prefix D:\OCaml ![Sans titre](https://us1.discourse-cdn.com/flex020/uploads/ocaml/original/2X/e/e20812623c17bcce5134603032ee179ef6b37308.png) but it is still being installed in the wrong drive and not in the one i have specified in the command you have just given me. I have only the uninstall.exe and app.ico files that are being installed in the D:\OCaml folder. ---

If you let it continue you’ll see that OCaml is installed in your D: drive but the prerequisites (Visual Studio and Git) have their own installers that install to default locations (C:). Can you make an issue? Not for your benefit but for every other first-time user. 90+% of them ask+search questions in the Issues ([Issues · diskuv/dkml-installer-ocaml · GitHub](https://github.com/diskuv/dkml-installer-ocaml/issues)) because that is what the installer tells them to do. ---

I have another folder called DiskuvOcaml that is roughly 2.5 Go that is being installed in C. If i have already (Git and VS), is it gonna install them again, if that’s not the case, can i install VS on its own and then install the OCaml Windows installer?
