To resolve this issue, use the Windows Vista Expand command to extract and to view the files in an MSU. The Expand command is included in Windows Vista and in the Windows Vista OEM Pre-installation Kit (OPK).
Note The Windows Vista Expand command differs from the Expand command that is included in earlier versions of Windows.

The .cab file that is extracted from the MSU file uses Intra-Package Delta (IPD) compression technology. IPD technology reduces the download size of an MSU but still delivers a self-contained package that contains the updated files. A .cab file that uses IPD is known as an "IPD-aware" package. Other programs and tools may be unable to extract or to view the files in the IPD-aware package that is contained in an MSU file.
For example, the following programs and tools cannot extract or view the files in an IPD-aware package:
