[Bug-gswin] bug report for gs800

[Alex Aris]

Symptoms:
---------

After installing ghostscript 8.00, I realized
that there was already versions 7.00 and 7.04.
So, I uninstalled them and then installed 8.00 again
to a different directory. I forgot that I already installed
8.00 . After I realized both installations, I tried to uninstall
8.00, and then install it to the old location (C:\gs) and uninstall,
install it to the new location (E:\gs) and then uninstall to clear up
everything.

However, after I uninstalled 8.00, and installed 8.00,
I couldn't uninstall it because the "Add/Remove Programs"
tool didn't even show gs 8.00 .
Now, no matter how hard I try to install  gs 8.00,
everything seems fine but nothing works. And the "Add/Remove
Programs" tool doesn't show it either.

I don't know how to clear up everything and install everything
again.

Suggested fix:

Checking whether the same version of gs exists and
not installing if so.

Checking whether previous versions of gs exist,
and warn to user about it before installing
(and also, at that point giving a chance to the user
 to exit setup so that s/he can uninstall the prev. version)
