Problem With Acrobat 4.0 + Update 1

[neo van matix 0]

Heyho...

currently im writing a unattended installation of Acrobat 4.0 and some Updates.

I've the problem, that after the installation of acrobat 4.0 and the Update, a Messagebox pops up into the foreground with the Titel "Information" and the Text "... congradulations ... ".

But AutoIt doesnt switch into the Box and ControlClick Button1.

Maybe someone can help ?

Acrobat 4.0:

$TITLE = "Informationen"
$TEXT = "Sie sich für Adobe Acrobat entschieden"
WinActivate($TITLE, $TEXT)
WinWaitActive($TITLE, $TEXT)
ControlClick($TITLE, $TEXT, "Button1")

Acrobat 4.0 Update 1:

$TITLE = "Information"
$TEXT = "Thank you"
WinActivate($TITLE, $TEXT)
WinWaitActive($TITLE, $TEXT)
ControlClick($TITLE, $TEXT, "Button1")
