Determine the version of the word installation
<![CDATA[
Question:
My Delphi application needs to verify that Microsoft Word is installed and it has to be at least Word version 2000. How can I do this?
Answer:
The function GetInstalledWordVersion creates a Word object and reads the version number from there. If creating the Word object fails, then Word is not (properly) installed, thus the function returns 0.
// ..
uses
ComObj;
const
Wordnotinstalled = 0;
Wordversion97 = 8;
Wordversion2000 = 9;
WordversionXP = 10;
Wordversion2003 = 11;
function GetInstalledWordVersion : integer;
var
Word: OLEvariant;
begin { GetInstalledWordVersion }
Result := 0; // Word is not installed
try
Word := CreateOLEObject('Word.Application');
Result := Word.version;
Word.Quit;
finally
Word := Unassigned
end;
end; { GetInstalledWordVersion }
begin
//..
if GetInstalledWordVersion < Wordversion2000 then
ShowMessage('You need a newer version of Word')
//..
end.
