ERROR_RELOC_CHAIN_XEEDS_SEGLIM
What ERROR_RELOC_CHAIN_XEEDS_SEGLIM means
ERROR_RELOC_CHAIN_XEEDS_SEGLIM is Win32 system error code associated with the documented message: “The operating system cannot run %1.” The significant condition is that a relocation chain extends beyond the bounds of the segment it is supposed to fix up. For ERROR_RELOC_CHAIN_XEEDS_SEGLIM, preserve the symbolic name together with the numeric value because older diagnostic tools may display only one form.
For ERROR_RELOC_CHAIN_XEEDS_SEGLIM, relocation processing adjusts addresses when the image is placed in memory. With ERROR_RELOC_CHAIN_XEEDS_SEGLIM, a malformed chain is an image-integrity problem: the loader cannot safely guess which fixups were intended.
Likely causes
- the relocation table is corrupt or truncated
- a packer or patcher changed segment offsets without rebuilding relocation chains
- storage corruption altered a relocation link or segment length
Diagnostic procedure
- validate every relocation-chain offset against its segment size
- compare relocation tables with a known-good executable
- remove post-link transformation and rebuild the artifact
During a ERROR_RELOC_CHAIN_XEEDS_SEGLIM investigation, capture the first operation returning ERROR_RELOC_CHAIN_XEEDS_SEGLIM. In the ERROR_RELOC_CHAIN_XEEDS_SEGLIM timeline, a later cleanup failure can be easier to notice while no longer describing the original defect. The evidence set for ERROR_RELOC_CHAIN_XEEDS_SEGLIM should record executable path, file version, architecture, Windows build, compatibility settings, and non-secret inputs used by the failing operation.
How to interpret the result in modern software
ERROR_RELOC_CHAIN_XEEDS_SEGLIM belongs to the 0–499 system-error range, but its wording may describe a historical subsystem. Do not classify ERROR_RELOC_CHAIN_XEEDS_SEGLIM automatically as a current Windows kernel defect. For ERROR_RELOC_CHAIN_XEEDS_SEGLIM, first determine whether the value came directly from GetLastError(), was translated from another status domain, arrived over a protocol, or was stored by an old application. Because ERROR_RELOC_CHAIN_XEEDS_SEGLIM can be propagated through wrappers, a missing producer API leaves translation errors and stale last-error values indistinguishable.
Code-specific investigation notes
Every relocation location must lie inside the segment being fixed. Once a chain crosses that boundary, following it could overwrite unrelated loader memory.
A safe validator stops at the first out-of-range link and reports the previous valid record, segment size, and offending offset.
If a custom patcher is involved, verify its behavior when segment alignment changes; unchanged logical offsets can become invalid after repacking.
Developer guidance
Code handling ERROR_RELOC_CHAIN_XEEDS_SEGLIM should check the exact API return first, copy the last-error value immediately, and avoid intervening calls before logging. If ERROR_RELOC_CHAIN_XEEDS_SEGLIM is raised by a loader or compatibility helper, collect parent-process diagnostics because the child may never initialize its own logger. For ERROR_RELOC_CHAIN_XEEDS_SEGLIM, validate format-specific fields with an appropriate parser; byte-level edits made only to suppress ERROR_RELOC_CHAIN_XEEDS_SEGLIM can turn a clean rejection into corruption or unsafe execution.
Administrator and support guidance
To recover from ERROR_RELOC_CHAIN_XEEDS_SEGLIM, prefer a matched trusted binary/configuration set over individual DLL downloads or global compatibility changes. Before replacing an artifact associated with ERROR_RELOC_CHAIN_XEEDS_SEGLIM, retain it and calculate a cryptographic hash. When ERROR_RELOC_CHAIN_XEEDS_SEGLIM is isolated to one account or session, compare mappings, namespaces, environment, current directory, and policy before considering system-wide reinstall.
Example incident
A post-build packer rewrites a legacy executable. The packaged file copies successfully, but its relocation data is inconsistent and startup stops with ERROR_RELOC_CHAIN_XEEDS_SEGLIM.
Difference from related errors
ERROR_INFLOOP_IN_RELOC_CHAIN detects a cyclic relocation chain; ERROR_RELOC_CHAIN_XEEDS_SEGLIM detects a chain that escapes the segment boundary.
Evidence to collect
- the raw decimal and hexadecimal value corresponding to
ERROR_RELOC_CHAIN_XEEDS_SEGLIM - the exact API, command, or loader action that first produced the result
- paths after normalization and redirection, plus hashes and versions of involved binaries
- process architecture, session identity, compatibility mode, and relevant virtualization details
- a timestamp that can be correlated with application logs, Process Monitor traces, and Windows Event Log
Recovery and verification
A ERROR_RELOC_CHAIN_XEEDS_SEGLIM repair is verified only when the original operation succeeds with equivalent inputs and produces usable output. After correcting ERROR_RELOC_CHAIN_XEEDS_SEGLIM, repeat the action in a fresh process and again in the same workflow to test both stale-state removal and repeatable cleanup. If reboot alone removes ERROR_RELOC_CHAIN_XEEDS_SEGLIM, collect enough evidence to identify which mapping, lock, process, or compatibility state the reboot cleared.
