Failed to load database information. Error in File temp_

Question

Our environment:
Windows Server 2012 R2 Data-center Edition 64 bit
Visual Studio Pro 2013 Version 12.0.3.30110.00 Update 1
.Net 4.5.51641
Crystal Reports for VS 2013 V13.0.9.1312
Oracle ODAC 11.2.0
We created a winform application to generate a form letter report that runs fine within the IDE. When we build the the exe and copy it from the project folder to a folder on the C:\drive of this same pc and try to execute it we get these error messages (partial list);
CrystalDecisions.CrystalReports.Engine.DataSourceException: Failed to load database information.

We have the CPU set to x86 as we are ultimately trying to generate a 32 bit app for XP and Win 7. We only installed the 32 bit run time on this pc because we have no intention of going to 64 bit apps on the clients. Are there additional dlls or something that has to be installed in the same folder as the exe on this development machine.

Looking at the AppData\Local\Microsoft\Windows\WER\ReportArchive\AppCrash_myprograminfo led us to the last dll loaded being:
LoadedModule[211]=C:\Program Files\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\crdb_adoplus_res_en.dll
State[0].Key=Transport.DoneStage1
State[0].Value=1
FriendlyEventName=Stopped working
Scanning the community for "crdb_adoplus_res_en.dll" we got a hot on this issue again:
Failed to load database information. Error in File temp_
From the above we found this:
1. the app.exe.config is all in one package which cannot be separated with the EXE file.
2. the supporting component such as dll files, app.exe.config etc CANNOT be combined into the EXE file
Adding the cr3Test.exe.config to the same folder as the cr3Test.exe RESOLVED the problem on Win 7. It also RESOLVED the problem on Server 2012 R2.
We still need to test on Server 2008 R2 but we are hopeful when that time comes.
Thanks.
