Detect whether Microsoft Word is installed?

[emendelson]

Over at CodeProject.com, someone posted this C++ code for testing whether Word is installed:

Type officeType = Type.GetTypeFromProgID("Word.Application");

if (officeType == null)
{
    // Word is not installed.
    // Show message or alert that Word is not installed.
}
else
{
    // Word is installed.
    // Continue your work.
}

I've been trying to figure out to do this in AutoIt, preferably using the COM interface, but I haven't managed at all. Does anyone know the quick answer to this problem?

Local $oWord = ObjCreate("Word.Application")

If IsObj($oWord) then
    ConsoleWrite ("ObjCreate: Version: " & $oWord.Caption & " " & $oWord.Version & " & Build: " & $oWord.Build & @LF)
    $oWord.Quit
EndIf

ConsoleWrite("RegRead: " & RegRead("HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths\winword.exe", "Path") & @LF)

Normally use '' for InunoTaishou second solution like so:

$hOffice = RegRead("HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths\winword.exe", "")
If FileExists($hOffice) = 0 Then Exit

However if you're coding for multiple versions of Office I normally  use this:

$hOffice_Version = 0
$hOffice = RegRead("HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths\winword.exe", "")
If FileExists($hOffice) Then $hOffice_Version = Round(FileGetVersion($hOffice), 0)
Switch $hOffice_Version
    Case 12
        ;~ Office 2007 Code here
    Case 14
        ;~ Office 2010 Code here
    Case 15
        ;~ Office 2013 Code here
    Case 16
        ;~ Office 2016 Code here
    Case Else
        ;~ Office not detected or unknown version
EndSwitch

That's very useful - thank you.  The second one shows me how to test for ancient versions that may not work with the procedures I'm using. Thank you again.
