About File Installation
The functions included in the file installation library determine where a file
should be installed, identify conflicts with currently installed files, and
perform the installation process. These functions enable installation programs to
avoid the following problems:
- Installing older versions of components over newer versions
- Changing the language in a mixed-language system without notification
- Installing multiple copies of a library in different directories
- Copying files to network directories shared by multiple users
The file installation library also includes functions that enable applications
to query a version resource for file information and present the information
in a clear format. This information includes the file's purpose, author, version
number, and so on.
Version information can be added to any Microsoft® Windows® file that can have Windows resources, such as a dynamic-link library (DLL),
an executable file, or a font file. To add the information, a developer must
create a version resource and add the resource to the file by using a resource
compiler and specifying VS_FILE_INFO as the resource type.
