Error: ESRIRegAsm.exe Error: Registration Failed. Could not load file or assembly
Error Message
When attempting to register or unregister an ArcObjects assembly created with a previous version of ArcObjects with version 10.3, the following error is returned:
"Registration failed. Could not load file or assembly 'Esri.ArcGIS.ADF.Local, Version=10.2.0.0, Culture=neutral, PublicKeyToken=8fc3cc631e44ad86' or one of its dependencies. The system cannot find the file specified."
For example, assume that a managed COM assembly, classlibraryfor102.dll, is being registeretd that was created with 10.2 and execute the following command line to register it with 10.3:
C:\Projects\ClassLibFor102\bin\Release> "C:\Program Files (x86)\Common Files\ArcGIS\bin\esriregasm.exe" classlibraryfor102.dll /p:Desktop
The following error message is displayed:

Cause
The ESRIRegAsm.exe.config file distributed with 10.3 is wrong. It currently references 10.2.0.0 and not 10.3.0.0 for the assembly binding redirection elements.
Solution or Workaround
- Download and unzip ESRIRegAsm.exe.config.zip to obtain a new copy of the ESRIRegAsm.exe.config file. Replace the existing file with this new version.
The default install location of the existing config file is:
• For 64-bit Windows operating systems: C:\Program Files (X86)\Common Files\ArcGIS\bin
• For 32-bit Windows operating systems: C:\Program Files\Common Files\ArcGIS\bin - After replacing the config file, re-execute the ESRIRegAsm.exe registration.
For example (using the same example as before):C:\Projects\ClassLibFor102\bin\Release> "C:\Program Files (x86)\Common Files\ArcGIS\bin\esriregasm.exe" classlibraryfor102.dll /p:Desktop
The following message should now be displayed:
