it's a bug from Adobe when you create AIP. Somehow, the wrong image inserted into the splash.dll (the embedded image is a PNG file stored within splash.dll. You can use Resource HAcker and extract it into PNG for confirmation). http://www.appdeploy.com/messageboards/fb.asp?m=62117 to "solve" this, install Acrobat 9 Pro Extended (from the CAB source). Go to the installed folder and copy out the splash.dll file. Next uninstall Acrobat 9 Pro Ext. In your AIP, go back to the Acrobat folder and replace the existing splash.dll with the one you copied earlier (via CAB installation). Do this *after* you have slipstreamed all the updates till 9.3.3. Also, the installer wont nag. Seems that it doesnt check the hash/filesize of this splash.dll.
