Issue in executing SSIS package using ASP.Net web forms.

I have SQL Server Integration services 10.0(SQL Server 2008r2)and 11.0(SQL Server 2012) running. We are executing SSIS packageusing ASP.NET Webforms. Executing fine,no issues. But the problemis,

whenever we uninstall 2008r2, it's not working and getting some error below:

System.Exception: Error in  Personnel conversion process The requested OLE DB provider isnot registered.If the 32-bit driverisnot installed, run the packagein 64-bit mode. Errorcode: 0x00000000.

whenever we uninstall 2012, it's not working and getting some error below:

WRN:Assemblybinding loggingis turned OFF.

Toenableassembly bind failure logging,set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog](DWORD) to 1.

Note: Thereissome performance penalty associatedwithassembly bind failure logging.

To turn this featureoff, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

I want to run the SSIS Package using ASP.NET Webforms.

It would be greatly appreciated your help me in resolving this.

Thanks
