I've installed the PostgresQL Database and the psqlODBC Driver.
Secondly Ive added a new "System Data Source" in ODBC Datat Source Administrator.
The test there has run successful.
Now I choose in "Data Link Properties" the Microsoft OLE DB Provider for ODBC Drivers
and choose the data source name, which Ive entered in the ODBC Data Source Administrator to make a Database Connection.
But when I test the Connection in Data Link Properties it fails with following error message:

"Microsoft Data Link Error

Test connection failed because of an error in initializing provider.

I tried the same on an Windows XP System and everything went fine.
I will be glad about any help and meaning...
