--- Comment #2 from Ivan Kazmenko <gassa at mail.ru> ---
Can't reproduce it here with a fresh install (Windows 2008 R2).
The baddest thing I got is:

-----
0. The system is clean from any D-via-installers (I myself use zip archives).

1. Run dmd-2.067.0.exe and follow the defaults.

2. Run dmd-2.069.0.exe, it asks to uninstall and runs the process
uninstall.exe.

3. Follow the defaults, it asks for recursive deletion (of the default path
C:\D\dmd2).

4. After clicking Finish, the 2.069.0 installer resumes, BUT there is a new
Au_.exe process (locally from
C:\Users\<username>\AppData\Local\Temp\1\~nsu.tmp\) which AGAIN asks for
recursive deletion of the default path.  Whatever I choose (OK or Cancel or
just ignore the Au_.exe window), the installer is able to proceed normally.
-----

If I replace dmd-2.067.0.exe with dmd-2.068.1.exe or dmd-2.068.2.exe on step 1,
there is no such effect.

Perhaps there exists a version to use on Step 1 which would help reproduce a
more severe problem?  Can't try all of them right now.
