VB – DataEnvironment will not work

I have used a DataEnvironment to connect to the database. Everything works perfectly when I run the app while in VB. However when I package it and install it, i get an error everytime the recordset.addnew event fires. Error is: “Class not registered.” Any ideas?
When I change to a diffent db connection method I can get it to work on the client. But I would much prefer to use the DataEnvironment. Please help. Thanx
