LNK1123: Failure During Conversion to COFF: File Invalid or Corrupt
“LNK1123: failure during conversion to COFF: file invalid or corrupt” link error when building a VC++ 2010 project.
This error can appear after installing Visual Studio 2012 side-by-side (SXS) with Visual Studio 2010 RTM or after installing .Net Framework 4.5 on a machine with Visual Studio 2010.
The issue is caused by a dependency failure of cvtres.exe on msvcr100_clr0400.dll which is shipped with Visual Studio 2010 RTM and eventually updated with a new version when Visual Studio 2012 RTM or .NET Framework 4.5 is installed.
To resolve this link error, upgrade Visual Studio 2010 RTM to VS 2010 SP1. Upgrading to VS 2010 SP1 resolves the dependency failure and the VC++ 2010 project builds with no LNK1123 error.
