Default Intermittent EOleSysError

I'm a new Delphi DB programmer and running Delphi 7, Windows 7 and MSAccess 7 and a Delphi program with no code, except for "end.". The db is in 2000 format and has one record with numerical data. Same db in 2007 format does not compile and will not show data in design time. Program has Datasource , ADOTable , and ADOConnection components.

When program is RUN this message appears: "Exception EOleSysError in module Proj1.exe at 00072771. Interface not registered." Msg disappears after several seconds and then program compiles and works normally.
If the program is then compiled again, there is no error message and it compiles ok.
Have unsuccessfully tried OleInitialize and OleUninitialize code and code to register OCX files recommended in other forums.

What needs to be done my me and potential customers, to eliminate this problem? Thanks for your help.
