Unable to get installer types error installing the Export Connector for ERP on Capture 10.1 or later


Question / Problem: 

When installing KCEC Export Connector ERP 2.4.9 with KC10.1 it fails with the message "Error 1001 - unable to get installer types in the c:\Program Files (x86)\Kofax\CaptureSS\ServLib\Bin\DicomPS.ERP.ReleaseScript.dll assembly --> unable to load one or more of the requested types. Retrieve the Loader Exceptions property for more information".

Answer / Solution: 

The problem is DicomPS.ERP.ReleaseScript.dll has a reference to Kofax.ReleaseLib.Interop.dll (compiled for .NET 2.0). But KC 10.1 and later have this dll compiled under .NET 4.x so, it is not found by the installer.

The following solution should resolve this:

On the Capture 10.1 or later machine, temporarily rename the Kofax.ReleaseLib.Interop.dll. This file is in the Kofax Capture executable folder usually here:

C:\Program Files (x86)\Kofax\CaptureSS\ServLib\Bin

Copy the file Kofax.ReleaseLib.Interop.dll from a Kofax Capture 9.0 or 10.0 machine and paste into the Kofax Capture executable folder.

The Install should work okay now. After the install is complete, rename the dll you just copied and then, rename the original dll back to it's original name.

Attached below is a copy of a Kofax.ReleaseLib.Interop.dll from a Capture 9.0 system that can be used for this solution.
