https://issues.dlang.org/show_bug.cgi?id=20489

          Issue ID: 20489
           Summary: Installer deleting files after install
           Product: D
           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: installer
          Assignee: nobody puremagic.com
          Reporter: simen.kjaras gmail.com

Something seems to be wrong with the 2.090.0 Windows installer. After
successfully installing, it proceeds to delete every file it has just added.

Looking closely at how it happens, it seems that it might actually be caused by
the uninstaller deleting itself and the directory it's in. If I wait long after
the previous version has been uninstalled before clicking 'next', it doesn't
happen.

So, how to reproduce:

1) have a previous DMD version installed
2) start the 2.090.0 installer
3) answer yes to uninstalling the previous version
4) quickly finish installing 2.090.0

If you do this with the install folder open in an explorer window, you should
see the files disappearing during the uninstall of the previous version, until
the only item in the D folder is uninstall.exe. As the new install proceeds
more files and folders will be added, and finally they will all be deleted
again, sometimes leaving an empty folders, other times a partial installation
(I've only once managed to get a partial installation).

It seems that the installer is not waiting for the uninstall to finish before
installing things, or conversely that the uninstaller signals completion before
it's actually done.
