Version: 1.0.12 (June-2013)
Verpatch is a command line tool for adding and editing the version information
of Windows executable files (applications, DLLs, kernel drivers) without rebuilding the executable.
It can also add or replace Win32 (native) resources, and do some other modifications of executable files.
verpatch filename [version] [/options]
* filename : any Windows PE file (exe, dll, sys, ocx...) that can have a version resource
* version : one to four decimal numbers, separated by dots, ex.: 184.108.40.206
Additional text can follow the numbers; see examples below. Ex.: "220.127.116.11 extra text"
Verpatch sets ERRORLEVEL 0 on success, otherwise errorlevel is non-zero.
Verpatch modifies files in place, so please make copies of precious files.
/va - creates a version resource. Use when the file has no version resource at all,
or existing version resource should be replaced.
If /va is not specified, verpatch will read and modify version resource from the file.
"value" - add a version resource string attribute
The name can be either a full attribute name or an alias; see below.
for list of known attribute name
/sc "comment" - add or replace Comments string (shortcut for /s Comments "comment")
/pv <version> - specify the Product version
where <version> arg has same form as the file version (18.104.22.168 or "22.214.171.124 text")
/high - when less than 4 version numbers, these are major numbers. By default, less than 4 numbers are minor numbers.
/fn - preserves Original filename, Internal name in the existing version resource of the file.
/langid <number> - language id for new version resource.
Use with /va. Default is Language Neutral.
<number> is combination of primary and sub-language IDs. ENU is 1033 or 0x409.
/vft2 num - specify driver subtype (VFT2_xxx value, see winver.h)
The application type (VFT_xxx) is retained from the existing version resource of the file,
or filled automatically, based on the filename extension (.exe->app, .sys->driver, anything else->dll)
/vo - outputs the version info in RC format to stdout.
This can be used with /xi to dump a version resource without modification.
Output of /vo can be pasted to a .rc file and compiled with rc.
/xi- test mode. does all operations in memory but does not modify the file
/xlb - test loopback mode. Re-parses the version resource after modification.
/rpdb - removes path to the .pdb file in debug information; leaves only the file name. This has no relation to the "original file name" attribute.
/rf #id file - add or replace a raw binary resource from file (see below)
/noed - do not check for extra data appended to the exe file (see below)
verpatch d:\foo.dll 126.96.36.199
- sets the file version to 188.8.131.52
The Original file name and Internal name strings are set to "foo.dll".
File foo.dll should already have a version resource (since /va not specified)
verpatch d:\foo.dll 1.2.33 /high
- sets three major 3 numbers of the file version. The 4th number not changed
File foo.dll should already have a version resource.
verpatch d:\foo.dll 33.44 /s comment "a comment"
- replaces only two minor numbers of the file version and adds a comment.
File foo.dll should already have a version resource.
verpatch d:\foo.dll "33.44 special release" /pv 184.108.40.206
- same as previous, with additional text in the version argument.
- Product version is also fully specified
verpatch d:\foo.dll "220.127.116.11" /va /s description "foo.dll"
/s company "My Company" /s copyright "(c) 2009"
- creates or replaces version resource to foo.dll, with several string values.
( all options should be one line)
verpatch d:\foo.dll /vo /xi
- dumps the version resource in RC format, does not update the file.
In "patch" mode (no /va option), verpatch replaces the version number in existing file
version info resource with the values given on the command line.
The version resource in the file is parsed, then parameters specified on the command line are applied.
If the file has no version resource, or you want to discard the existing resource, use /va switch.
Quotes surrounding arguments are needed for the command shell (cmd.exe), for any argument that contains spaces.
Also, other special characters should be escaped (ex. &, |, and ^ for cmd.exe).
Null values can be specified as empty string ("").
The command line can become very long, so you may want to use a batch file or script.
See the example batch files.
The Version argument can be specified as 1 to 4 dot separated decimal numbers.
If the switch /high is not specified and less than 4 numbers are given,
they are considered as minor numbers.
The major version parts are retained from existing version resource.
For example, if the existing version info block has version number 18.104.22.168
and 55.66 specified on the command line, the result will be 22.214.171.124.
If the switch /high is specified and less than 4 numbers are given,
they are considered as higher numbers.
For example, if the existing version info has version number 126.96.36.199
and 55.66 /high specified on the command line, the result will be 188.8.131.52.
Additional suffix can follow the version numbers, separated by a dash (-) + or space.
If the separator is space, the whole version argument must be enclosed in quotes.
Verpatch ensures that the version numbers in the binary part
of the version structure and in the string part (as text) are same,
or the text string begins with the same numbers as in the binary part.
But the string representation of file or product version will not be displayed by Windows Explorer in Vista or newer. The file version displayed will always have 4 parts and no suffix.
The /high switch has been added to support the "Semantic Versioning"
as described here: http://semver.org
The "Semantic versioning", however, specifies only 3 parts for the version number,
while Windows version numbers have 4 parts.
Switch /high allows 3-part version numbers with optional "tail" separated by '-' or '+'.
By default, Original File Name and Internal File Name are replaced by the actual filename.
Use /fn to preserve existing file names in the version resource.
String attribute names for option /s must be language-neutral,
not translations (example: PrivateBuild, not "Private Build Description").
for the list of known attributes names and their aliases.
The examples above use the aliases.
String arguments for File version and Product version attributes are handled
in a special way, the /s switch should not be used to set these:
- The File version can be specified as the 2nd positional argument only
- The Product version can be specified using /pv switch
Adding binary resource from file
The /rf switch adds a resource from a file, or replaces existing resource with same type and id.
The argument "#id" is a 32-bit hex number, prefixed with #.
Lowest 16 bits of this value are resource id; can not be 0.
Next 8 bits are the resource type: one of RT_xxx constants in winuser.h, or user defined.
If the type value is 0, RT_RCDATA (10) is assumed.
High 8 bits of the #id arg are reserved0.
The language code of resources added by this switch is 0 (Neutral).
Named resource types and ids are not implemented.
The file is added as opaque binary chunk; the resource size is rounded up to 4 bytes
and padded with zero bytes.
Removing path to the debug information file (pdb)
This was added for these who consider the full path to the pdb file stored in the executable sensitive information (or use embarrassing names for their project directories).
Option /rpdb changes the path to the .pdb file to "x:\" followed by the original PDB file name. This will not break the association of the PDB file with the executable. It still can be used to debug, if the actual path is specified to the debugger.
Preserving extra data appended to executable
Verpatch detects extra data appended to executable files, saves it and appends
again after modifying resources. Command switch /noed disables checking for extra data.
The extra data is any data following the last section described in the PE header.
Such extra data is used by some installers, self-extracting archives and other applications.
However, the way we restore the data may be not compatible with these applications.
Please, verify that executable files that contain extra data work correctly after modification.
Make backup of valuable files before modification.
Note: digital certificates appended to the file cannot be reliably removed by /noed; this issue may be fixed in next releases. For now, use "delcert" utility (google) to remove certificates from a file before using verpatch on it.
