INF Validation Errors and Warnings

  • Article

This topic describes driver installation errors and warnings that can appear as a result of the automatic INF verification that Microsoft Visual Studio performs, or when you run the InfVerif tool.

Starting in Visual Studio 2015 with WDK 10, when you build your driver, the following INF file errors can appear in the Error List pane. If you are running InfVerif.exe from the command line, the tool displays these errors at the command prompt, or in the HTML version of the results.

Error Guidance

InfVerif follows a general rule that the lower the error number, the more severe the issue. Most error codes can be either a warning or an error depending on the arguments supplied to InfVerif.

Errors should be considered "must fix".

Warnings can be ignored if they are fully understood, but they are often symptoms of another problem. For instance, a warning about a section being unused could be a symptom of an INF directive being invoked incorrectly.

Handling Errors

You must fix all errors in order to pass driver tests in Hardware Dev Center.

Errors are related to the following conditions:

  • The INF parser is unable to successfully interpret your INF
  • The INF parser is able to interpret the INF only by making a default value assumption (ambiguous syntax)
  • The arguments to InfVerif indicate that a rule set should be applied to the INF (such as InfVerif /h)

While you don't need to fix warnings before submitting your driver on the Dev Center, we recommend taking the time to understand the issue being reported. If you don't understand a given warning, your INF might not always behave as you expect.

Warnings are typically related to:

  • Syntax that may be incorrect but has valid scenarios where it is appropriate
  • Syntax that is valid for the given InfVerif parameters but is an error in other modes, such as Driver Isolation mode

Error Codes

In WDK 10.0.26100.1 (Windows 11, version 24H2), InfVerif.exe command 'infverif.exe /code' has the same information as the below table.

The syntax '<value>' was introduced in OS version <value>.<value>.<value>, but DDInstall sections utilizing the syntax will install on earlier OS versions. Those DDInstall sections should be restricted to only install on <value>.<value>.<value> or higher using a TargetOSVersion decoration.

Details
The impacted DDInstall section will install on product versions that do not support the specified syntax. A build
number should be added to the Models section to limit applicability of the DDInstall to only supported product
versions. This will prevent the driver from installing on product versions where it will not function properly.

The specified file operation required a name to be specified, but it was not specified.		 /k: Error
/u: Error
/w: Error
Code 1230

Message
Missing file '<value>' under [SourceDisksFiles] section.

Details
A file was specified in a CopyFiles or similar directive but could not be found in the [SourceDisksFiles] section,
or the listing in [SourceDisksFiles] was invalid.

This error frequently occurs when architecture-decorated versions of [SourceDisksFiles] are specified
(such as [SourceDisksFiles.amd64]), but not all architectures supported by the INF have a [SourceDisksFiles] section.		 /k: Error
/u: Error
/w: Error
Code 1231

Message
Invalid compressed filename '<value>' specified under [SourceDisksFiles] section, expecting uncompressed filename '<value>'.

/u: Error
/w: Error
Code 1235

Message
String token '<value>' not defined in [<value>] section - if intending to use a literal '<value>' in a string, use '<value>' instead.

Details
A specified string token has no definition in the [Strings] section. For example, the INF file specifies %REG_DWORD%
in an add-registry section specified by an AddReg directive, but there is no corresponding REG_DWORD = 0x00010001
in the [Strings] section.

This error frequently occurs if your INF file specifies a registry value that contains an environment variable. For example:
[MyAddReg]
HKR,,DllPath,%SystemRoot%\System32\binary.dll

The %SystemRoot% path component is interpreted as the "SystemRoot" string substitution token from under the
[Strings] section, rather than the intended behavior of storing the literal "%SystemRoot%" in the registry. To
use the literal value %SystemRoot% rather than perform a string substitution, use the escape sequence %%.
[MyAddReg]
HKR,,DllPath,%%SystemRoot%%\System32\binary.dll

the driver more robust against environment changes.		 /k: Error
/u: Error
/w: Error
Code 1258

Message
File path "<value>" in <value> may be incorrect in some device installation scenarios or contexts, use <value>\<subdirectory> instead.

Details
Use a runtime-resolvable path such as %SystemRoot% for values stored in the registry. DIRID values may be fully
resolved at the time the driver is added to the image. When the driver INF is processed under different deployment
scenarios (such as offline imaging or OS upgrade), an incorrect value may be stored.		 /k: Error

Message
Hardware '<value>' does not have an associated service using install section '<value>'.

Details
Starting in Windows 10, version 1809, this has changed from a Warning to an Error. The .Services sections are
required for each defined target OS. This is good practice even prior to 1809.

If an INF previously did not include this section because it relied on Microsoft-supplied Inbox driver services,
then a .Services section that references a .Services section from a Microsoft-supplied Inbox INF using Needs
and Include directives should be created. For example:
[DDInstall.Services]
Include=filename.inf
Needs=inf-section-name.Services

For devices that do not require a function driver, this can be specified as follows:
AddService = ,2

Only use this in the case where the INF is installing a device that does not need a function driver. For example,
a device that requires only a filter driver, but not a function driver would have two AddService directives:
AddService = MyFilterDriver,, My-Service-Install-Section
AddService = ,2
 /k: Error
/u: Error
/w: Error
Code 1297

Message
Device driver does not install on any devices, use primitive driver if this is intended.

Details
This indicates that the INF file is a device driver, but it is not being used as a device driver. This may cause
issues in how the driver is treated by the driver store. If this is unintentional, check your INF to make sure
that hardware IDs are correctly specified. If the driver is not intended to install on devices, convert it to a
primitive driver. A primitive driver is a driver that installs on the whole system instead of on specific devices.
