I unintentionally deleted the directory!!!

["Jamiil Abd Al Qadir" <arbolone gmail com>]

After
installing GTKmm in my MSWinXP box I unintentionally deleted the
directory, I had also isntalled GTK+ in same directory. When I tried to
reinstalled GTKmm, it did installed but without asking me to install
GTK+ first, as it always did before! I am trying to reinstall in the
same directory of the previous installation and then use the its own
uninstaller in an attempt to remove the previous installation, but to
no avail.
How can I correct the mistake I made?

Thanks in advance
