Error updating 1.1.15 to 1.1.16

Hi.
I have a new problem with the new update.

I will try to explain what I did it:
I deleted files of "/var/www/imscp/gui/public/tools/filemanager/" and create a new index.php with a header();

I also did it before update to 1.1.15

When I tried to update to 1.1.16 it show me a message error (attached file).
Everytime I try update, it delete a parent directory (filemanager, after tools, and finally public).

To try to solve it, (the first time) I copied to filemanager the content of net2ftp with my configuration (I use it in other subfolder), but It doesn't work.

Any idea?

Thanks in advanced.

I executed the command 5 times, everytime show the same error.

Why 2 dislikes from staff? What I do it bad? I have to no report the bugs?

Okay, sorry for report bugs.

I'm will try to reinstall old version or format the computer if it not fix.

regards .

1rst: Can I wrote all in spanish? Maybe it will be more comprensible.
2nd:The directory /var/www/imscp/gui/public/tools not exist (I said in the first post)
3rd: perl imscp-autoinstaller -dc not exist, is without er.
4th: I use this tutorial: http://wiki.i-mscp.net/doku.php?id=start:upgrade:debian, but with -c it works, thanks.

And finally, thanks to all for the dislike.

And thanks for the help (really).

I already installed
I mean it does not exist autoinstaller, the file is autoinstall, the other is a directory.

All already working.

Sorry for my bad, very bad english. I do what I can.
