'MSDAORA' provider is not registered on local machine

edited Jan 14, 2013 8:14AM in Oracle Provider for OLE DB

i have an app in which is connecting to a oracle database with a oledbconnection

Dim m As New OleDb.OleDbConnection("Data Source=...;Persist Security Info=True;User ID=...;Password=.........;Unicode=True;Provider=MSDAORA")

I developed with visual studio on a 32bit windows xp and when i debug my application everything is working fine.

Now i moved my app on a windows server 2008 64 bit version and implemented my app with iis 7.0

Now the problem is, everytime i start the app in my browser i get the following error:

System.InvalidOperationException: The 'MSDAORA' provider is not registered on the local machine

The connection to oracle can't be the fault. I can connect to oracle with sqlplus.

What is the error? What am I doing wrong?

Thanks for the help
