Virtualization

hi,
I have package which communicates with oracle clients at the back end or we can say some how it needs to communicate with oracle 10g to retrive some data. I'm using thinapp and my package.ini file is in merged mode. The app works fine for the users who have admin rights. the user who does not have admin rights are having issues as the package can't communicate with the oracle clients..
i'm sure the error is some thing with respect to ODBC settings .i'm not sure how to approach.can u guys help me abt this this is important...
NAME OF THE APP IS BUSINESS OBJECTS XI 3.1
THANKS --USHA
