When I am debugging a vb.Net 2008 windows application and click on the
'next' button, I am getting the following error:
'An unexpected error has occurred. The 'Microsoft.jet.oledb.4.0'provider is
not registered on the local machine'.

I think that I may need to change some setting I have in the visual
studio.net
2008 professional edition to solve this problem.

I am working on an workstation that is 64 bits, XP operating system. When
the click event has occurred, I have just attached an excel 2003 spreadsheet
to a file in the general directory structure prior to clicking on the 'next'
button.
This application runs fine in production, this error just occurs in debug
mode.
Thus can you tell me what I could change to fix my problem?

Is the production machine also 64 bit? What is the compile target for your
app (AnyCPU, x86, x64)?

The Jet engine is not available as a 64 bit version. You must compile your app
as a 32 bit application.
(configuration manager -> "active platform:" <New...> -> "new platform:" x86,
check "[X] create new project platform" -> OK)
