Microsoft Windows Installer Downloads

The new multi-package transaction introduced in Windows Installer 4.5 enables creating a single Windows Installer transaction from separate packages.

As a result, developers can now divide their products into multiple packages that can be composed and retain the robustness of the Windows Installer transaction.

A common example of this delivering language specific products in two packages, one language neutral World Wide package and one language specific package.

Support for Multi-Package Transaction is provided via new APIs MsiBeginTransaction, MsiEndTransaction, and MsiJoinTransaction.

In creating this multi-package transaction support, Windows Installer is further formalizing the role of a chainer in the application installation and servicing stack.

Windows Installer 4.5 adds the new MsiEmbeddedUI and MsiEmbeddedChainer tables to support embedding the binaries that were previously required to be external to the MSI.
