The SourceDir property is the root directory that contains the source cabinet file or the source file tree of the installation package. This value is used for directory resolution.
The directory that contains the installation package.
The ResolveSource action must be called before using the SourceDir property in any expression or attempting to retrieve the value of SourceDir with MsiGetProperty. The ResolveSource action should not be run while the source is unavailable, such as when uninstalling an application, because this can cause an unintended prompt for the source media.
