Sorry but I haven't been able to solve the problem yet.

The User Preferences listing runs OK
so that means the Crystal Runtime install is OK, and the issue is with the ODBC part.

I checked that the ODBC files MSVCR110.DLL and MSVCP110.DLL are in the C:\Windows\SYSWOW64 directory.

I ran OCSTEST.EXE to test the ODBC Connection String, using a sample string as described in the help document. I get the message: Unable to create connection!

FYI, here is the actual connection string that I tested it with:

DRIVER=AdagioDataSourceDriver;
DBQ=C:\SOFTRAK\Receivables\SAMDATA SAM;
DESCRIPTION=Adagio ODBC v2 Driver;
DBDIRECTORY=C:\SOFTRAK\Receivables\SAMDATA;
COLUMNS=COMMON;
DBFILTER=AR9*;
DBSELELECTOR=SAM;
NAMES=LONG;
TABLESALL=FALSE;
USERID=SYS;
PASSWORD=SYS;
RAWPASSWORD=1;
