Note
This feature was developed and tested with the RC1 build of Windows Installer 3.0;
unexpected results may occur with the final version of the runtime. As of this release of Wise
for Windows Installer, Microsoft had not released the final version of Windows Installer 3.0,
therefore, it is not included in this product. To use this feature, obtain an RC or production
build of Windows Installer 3.0 from Microsoft and install it on your computer.
