Windows Error Code Lookup

Decode Windows error codes: Win32, HRESULT (0x80070005), NTSTATUS, Windows Update, msiexec and blue-screen stop codes, with what to check next.

Paste the number from an error dialog, event log, script or setup log: 0x80070005, 80070005, -2147024891, 1603, 0xC0000005, a stop code like 0x7E, a name like E_ACCESSDENIED, or a few words. You get every way Windows could mean that number (an HRESULT often wraps a Win32 error, so 0x80070005 is "Access is denied" too), its parts decoded, and what to check for the common ones. Names and messages come from the Windows SDK headers and Windows' own message tables; see Microsoft's System Error Codes and [MS-ERREF] for the full references.

Try: 0x80070005, 1603, 0xC0000005, 0x800F081F, 0x8024402C, 0x7E, access denied

0x00000005 = 5

Win32 error 5 (0x5)

ERROR_ACCESS_DENIED

Access is denied.

The account doesn't have permission. Check NTFS and share permissions, whether the program needs to run elevated, whether the file is read-only or in use by antivirus, and, for a service or task, which account it runs as.

As an HRESULT (HRESULT_FROM_WIN32): 0x80070005E_ACCESSDENIED: General access denied error

If it's a robocopy exit code

Success, with files copied and mismatches.

1 Files copied: One or more files were copied.
4 Mismatches: Some files or folders didn't match their counterpart (for example a file in one place and a folder of the same name in the other).

Robocopy's exit codes are bit flags, not Windows errors: 0-7 mean it worked. Robocopy Command Builder.
