I wish I had a 64bit machine here and a sql server to test your problem. I no longer work for SC State gov but many of my ADO Sql Server apps live on in that environment.
I Googled the subject
sqloledb for windows 7 64 bit
and got several ideas .. From what I can tell SQLOLEDB should work with your app on 32 or 64 bit Windows 7 platforms .. some suggestions were to right click on the app and "run as administrator" .. or possibly your Windows user needs to be an administrator of their box and not a Std or limited user.
Or try using the Native SQLOLEDB
Provider=SQLNCLI11

I would be most curious how you solve this.
