Files Schema
Adaptive, depending on the number of files.
If this option is used, the msi schema is modified automatically, depending on whether your package contains more than 32767 files or not.
Always consider large number of files.
MSI schema for more than 32767 files is always used.
Patches cannot be created between two packages with different
schema types.
Database Encoding
Build language specific codepage
This option will allow your package to display only characters that are in the build language's codepage.
UTF-8 codepage
The installation database will be built using the UTF-8 encoding. That will allow you to mix any languages both in displayed text and installed resources (like files, registry... ).
Unicode characters may not display properly because the correct
font for wide characters is not chosen correctly in cases like when
performing a basic user interface install or uninstall.
