Pressing the PO Search button on the POEntry form in base-mode-only produces this error:

Application Error

Exception caught in: Erp.UI.POEntry

Error Detail 
============
Message: Could not load file or assembly 'Erp.Adapters.ConfigurationRuntime, Version=10.1.400.0, Culture=neutral, PublicKeyToken=5d3fa3c7105d7992' or one of its dependencies. The module was expected to contain an assembly manifest.
Program: Erp.UI.POEntry.dll
Method: OnButtonClick

I notice the error has Version=10.1.400.0 but I'm not sure that is causing the problem. I searched this forum and found something similar,  Jose suggested "recompiling the application" but I do not know what that means.  

I searched the client folder and found most of the DLL's have a date of 12/3/2015.  But some, including PO Entry have a date of 8/31/2016.   I checked the DLL's for version 9.05.603 and they all have the same date.  Did I go through a bad upgrade/patch or am I barking up the wrong tree?  

Please let me know if I should post a call to Epicor before asking questions on this forum.   Thanks in advance.

I'd have to guess its a bad client.  Have you tried another PC or the server's local client to see if it works there?  Either that or re-deploy the client to the machine and see if it works there.

It worked on another PC.  Rebooting the problem PC resolved the issue.  Strange.
