Long File Names and 16-bit Applications

InstallShield 2023

You can launch 16-bit applications using long file names, but you cannot pass long file names as arguments to 16-bit applications; 16-bit applications require the short file name versions of long file names to function correctly.

If your installation passes a file name to a 16-bit application, you must provide a valid short file name to the application. Long file names will not work.

If your installation writes file names to files such as .ini files, and if 16-bit applications are expected to use the files, you must write short file names that the 16-bit applications can use.
