MDAC required

Hi,

I have an application (that I wrote) that use ADO.NET to access an JET
(Access) database. My application was working fine, until I installed
and uninstalled a trial version of Microsoft Office 2007. I don't know
if it was working between the installation and uninstallation of office,
because I didn't tried it.

Now, it does not work anymore. I get this error (translated from french)
: The .Net Framework Date Providers requires Microsoft Data Access
Components(MDAC). Install Microsoft Data Access Components (MDAC)2.6 or
later.

Of course I tried to install MDAC 2.8 SP1, but it says I don't need it
since my OS already have. So I looked on the web and found a way to
install it anyway. The installation seemed to work, but it did not
resolve the problem. I uninstalled en re-installed the .Net Framework.
It did not helped either.

So the situation is I _seem_ to have a valid installation of MDAC 2.8,
but my dotnet 2.0 application keep complaining that it need me to
install MDAC 2.6 or higher.

What should I try next?

In advance, thanks for your help.

What provider are you using to connect to JET?

JET isn't part of MDAC anymore - it is a separate install.
