SYSDIFF /INF Uses Decimal Format for REG_DWORD Values

ID: Q197161

The information in this article applies to:

Microsoft Windows NT Workstation version 4.0
Microsoft Windows NT Server version 4.0

SYMPTOMS

When you create an .inf file from a SYSDIFF package, registry values in the package will be 0 after running the .inf file when the value in the .inf file is bigger than 2147483647.

CAUSE

When a registry entry contained in a SNAP file is written to an .inf file using the SYSDIFF /INF syntax, REG_DWORD values are written in decimal form. For example, 0x80000010 is written as 2147483664.

When Setupapi.dll runs this .inf file, it checks whether decimal REG_DWORD values exceed 2147483647 and writes 0 to the registry. SETUPAPI checks the value because all decimal values are supposed to be signed integers and, therefore, an overflow occurs.
