I don't think that firebird requires a client install.
All you need to do is to put a copy of gds32.dll in
the application folder.

Abort the install?  Isn't that a little
harsh?  As a <BR>
consultant/contractor/computer guy, I would like to
have the option <BR>
of including the install file in my setup, and then my
install simply <BR>
runs that program to make sure that the client is
installed <BR>
correctly, without having to reinvent the wheel. 
If it simply aborts, I <BR>
can't do that.   Could you document the
process untaken by the <BR>
installer so that it could be merged into another
install process.<BR>
Here are a few other options, they are all correct
actions, it <BR>
depends on what the Wise Installer is capable
of.  It should be <BR>
documented as to which one you decide to use, there
may also be <BR>
others, feel free to use any of these, or come up with
1) Rename the existing gds32.dll to gds32_dll.old and
write the <BR>
new one.  If this isn't what the user wants, the
user can simple <BR>
delete the FB one, and rename the old one back.<BR>
2) Change gds32.dll so it reflects the same version
number as the <BR>
Borland one, with a different build number. 
Since it now checks as <BR>
V6 it should not be a problem.  The version
resource would have <BR>
other information that reflects the true version
3) Give the installing person a pop-up that asks if
they want to <BR>
overwrite it or not.  Could be combined with
1and/or 5 or 6..<BR>
4) Add an install option, that asks if the user wants
to skip the  <BR>
version check for gds32.dll, during the install. 
Could be combined <BR>
with 1and/or 5 or 6.<BR>
5) Store the new gds32.dll as gds32_dll.fb and let the
user rename <BR>
it themselves.<BR>
6) Create a directory called \windows\system\fbbackup
move the <BR>
old gds32.dll to this directory and write the new one
in the correct <BR>
