The Microsoft Jet database engine cannot open the file '(unknown)'.

[Paul]

Hello,

I know there are other messages concerning this error message, but they
all look so confusing to me.

I have an application that uses an Access database. No problems with
permissions.
I made a windows service of that application.
I choose 'ServiceAccount.LocalService' in the ProjectInstaller (VS.NET)
which means Anonymous User.

Whith the application as a service a get the errormessage
"The Microsoft Jet database engine cannot open the file '(unknown)'.".
This is clearly a permissions problem to me.

I cannot figure out which permission settings I should change.
Is there anyone who can help me with this ?

Thanks for any help,

Paul

The account under which your service is running will require full permissions to the folder where
the Access database is located.
