With the rt_version utility, you can insert and edit Win32 version resources in PE32, PE32+ and RES files and version attributes in .NET assemblies.

Command-line syntax:

filename - path and name of the PE32, PE32+, RES file or .NET assembly.

If the file name or a parameter of an option contains spaces, it must be enclosed in quotes. For example:

Running rt_version without parameters displays help on the command-line options.

General options:

• [] - optional parameter.
• -q - quiet mode.

• -fv:%d.%d[.%d] - set version number.
• -gfv - read version number.
• -pv:%d.%d[.%d][.%d] - set product version.
• -gpv - get product version.
• -l:%language - set the language for the strings in the version resource.
• -fd:"%s" - set the 'FileDescription' string.
