          Issue ID: 23642
           Summary: DMD installer should set up PATH in the same order as
                    it was before reinstall
           Product: D
           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: installer
          Assignee: nobody@puremagic.com
          Reporter: andrej.mitrovich@gmail.com

It seems that reinstalling DMD on Windows will cause it to first uninstall and remove DMD from PATH, and then install it and add DMD to PATH as the *last* entry.

This can cause unexpected problems, for example:

- If there is no user-provided dub settings file (https://dub.pm/settings)
- And if another D compiler is installed and is in PATH, e.g. LDC
- And if the DMD was in PATH before LDC

Then after installing a new version of DMD via the installer the LDC compiler will be picked up by default by DUB.

Of course one can set up the default with https://dub.pm/settings, but the user may not be aware of that.
