Generally speaking that will work for you. The only areas that I wonder about
is did you mean Application.path or thisworkbook.path? Application.path is
the directory where the Excel.exe file is stored and normally you do not save
a lot of stuff in there... (not necessarily wrong, just curious). The other
comment is that you do not need to do that as an if - then - else. It could
be written

If Len(Dir(Application.Path & "\" & "abc.exe")) = 0 Then Exit Sub

etc

Can I reliably assume that Exit Sub will only occur if the file 'abc.exe' is
not found in the Office-installed path?
....not a trick question, just wish to know what I can be sure of, if I make
the statement.

Many thanks.
I'm trying to check the file exists... so
If abc.exe exists 'ok
Else MsgBox "You need to install abc.exe"
Exit Sub
End If
was my logic.

There are actually 2 files I'm looking for. I believe both are Optional
rather than Default choices during an Office install. I believe both files
(if installed during the initial Office install .... or later, via
Add/Remove Features) will
reside in Application.Path. However there may well be Office version issues
to deal with.

What do you think, please?

Regards.

That logic looks good. If you are looking for two files why not something like

If len(dir(ABC.exe)) < 0 and len(dir(CDE.exe)) < 0 then
'both files exist
'Do whatever you want to do
elseif len(dir(ABC.exe)) = 0
msgbox "ABC.exe does not exist"
else
msgbox "CDE.exe does not exist"
endif

Gets rid of that sometimes pesky exit sub... As for the files existing in
the application directory that sounds entirely resonable to me.

Thanks again.
I actually had:
If Len(Dir(Application.Path & "\" & "makecert.exe")) _
= 0 _
Or Len(Dir(Application.Path & "\" & "signer.dll")) _
= 0 Then
MsgBox "etc"
Exit sub
Else
etc
end If

BTW a very big help: where can I download 'signer.dll'?
I'm trying to develop a wrapper by which I can create
Self Certificates.....cannot find this file anywhere (thought it was with
SDK).

Regards and thanks again.
