MSIUpgradeCode Parameter
The MSIUpgradeCode parameter specifies a code for the MSI database that facilitates updates. When two
packages, such as the version 1.0 package and the version 2.0 package, have the same upgrade code, the MSI
installer detects this link, uninstalls the earlier package, and installs the updated package.
The capture process generates a random upgrade code based on the inventory name. To ensure that the MSI
database versions have the same upgrade code, keep the same inventory name across versions of the
MSIwrapper. For information about the inventory name, see “InventoryName Parameter,” on page 75.
The parameter is applied only when the MSIFilename parameter requests the generation of a Windows Installer
database.
NOTE Do not modify the UpgradeCode value unless the new value is a valid GUID.
Example: Creating an MSIFile using MSIUpgradeCode Parameter
The capture process can create an MSI file with D89F1994-A24B-3E11-0C94-7FD1E13AB93F as the upgrade
code.

MSIFilename=mymsi.msi

MSIStreaming Parameter
The MSIStreaming parameter determines the use of .cab files that can affect application performance.
The default setting is MSIStreaming=0. With this value, the packaged .exe files and .dat files are compressed
in the .cab file. Disabling the parameter in Package.ini has the same effect as setting the value to 0. When the
MSI runs, the packaged files are extracted to the Program Files directory of the Windows operating system,
and registered either to the user or the system, depending on other Package.ini settings.
Setting the parameter value MSIStreaming=1, results in the packaged.exe files and.dat files being excluded
from the .cab file, and subsequently from the .msi file. This value enables a choice to be made during
deployment between registering the application from a network share or installing in theProgram Files
directory of the Windows operating system.
If you set this value, ensure that both the MSI and the .exe and .dat files of the ThinApp package are available
on the network share.
Example: Modifying the MSIStreaming Parameter
You can modify the MSIStreaming parameter to ignore a .cab file when it slows down the installation process
for applications. You can distribute the MSI file and individual executable files in the /bin directory to install
the application.
