An error occured while creating the new dataset Could not get type informat

Question

Uses: Windows XP Pro SP3+; OracleXE; Oracle 8i Client; ODP.NET; Visual Studio 2005 PRO;
I had OracleXE and was using OracleXE's Oracle.DataAccess Version 10.2.0.100 which was located in C:\oraclexe\app\oracle\product\10.2.0\server\BIN. Then to use Oracle Developer Tools for VS, I installed ODAC where the Oracle.DataAccess's version was 2.111.6.20.
Everything connected via SqlPlus and even was able to Oracle XE Home page and was able to loginto it. Further, was even able to create connection with Oracle Dot Net Provider. The problem was created when I tried to create a datasource from DataSource Menu in VS.2005. It was giving an error saying "An error occured while creating the new dataset Could not get type information for dataset". However I wittnessed that Dataset is been created in Solutions Explorer but not in Data Source Tab. Further researching I was able to create Datasets with Microsofts Oracle Data provider with out any issue.
My Path variable list the following:
C:\app\Administrator\product\11.1.0\client_1;
C:\app\Administrator\product\11.1.0\client_1\bin;
C:\oraclexe\app\oracle\product\10.2.0\server\bin;
C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\;
C:\Program Files\Borland\BDS\4.0\Bin;
C:\PROGRA~1\Borland\Delphi5\Projects\Bpl;
C:\PROGRA~1\Borland\vbroker\jre\Bin;
C:\PROGRA~1\Borland\vbroker\Bin;
C:\PROGRA~1\Borland\Delphi5\Bin;C:\orant\bin;
C:\WINDOWS\system32;C:\WINDOWS;
C:\WINDOWS\System32\Wbem;
c:\Program Files\Microsoft SQL Server\90\Tools\binn\;
C:\Program Files\Microsoft SQL Server\80\Tools\BINN;
C:\Program Files\java\jdk1.6.0_07\bin.
Further I got 2 Oracle Homes one which C:\orant and other is located in C:\app\Administrator\product\11.1.0\client_1.
Also noted that while deploying at client site I started gett'n this error:
"Unable to install or run the application. The application requires that assembly Oracle.DataAcces version be installed in Global Assembly Cache First."
Is it due to change in the production machine? Any help in this regard is greatly appreciated.

Hi Pushpa,
Which enhancement package are you on currently? This is observed in cases where originals in DIR's are invisible and sometimes error message 26296 occurs in transaction CV01n. Hence,please check your entries in the table SDOKPROP to avoid such a problem in your system.
Further,suggest you explore if the below resolutions can be adopted in your case.
