Adobe Acro 8: Update of AcroPro.msi on AIP fails with windows installer error.

[_DPE_]

Hi,

Creating a AIP with Adobe Acrobat 8 files.
Have created a AIP without any problems.

When i try to add patches to the AIP using the MSIEXEC /a "" /p "" i get a Windows Installer error saying:

"This package could not be opened. Verify that the patch package exists and that you can access it, or contact tha application vendor to verify that this is a valid Windows Installer patch package."

What can be the cause of this?
The update packages are fresh downloads from Adobe.com.
Using WinXP SP3 with Windows Installer 4.5.
