InstallShield 2016 » InstallScript Language Reference
The VerGetFileVersion function retrieves the numeric version information of the specified file.
Note • Although InstallScript's file version functions take version information in string format, the version information they reference in a file is the numeric version information. A file's string version information is not inspected or returned by InstallScript functions. Further, when Windows Explorer displays a file's properties, it shows the string version information, which might not be equivalent to the file's numeric version information. For that reason, the value returned in svVersionNumber by VerGetFileVersion might not match the version information displayed by Windows Explorer.
For more about file version information, consult the Windows documentation.
