ImageUploader 4.7 activeXControlVersion - supportImageUploader

Hi,
I did update to 4.7 version. Under IE7, XP SP2 I have problem.
When Im loading page, IE is trying install new Activex version of uploader but SCRIPT below is detected that uploader is installed yet.
then my warnings under "supportImageUploader" are not displayed for users.

thanks
Marcel
