A family of Microsoft relational database management systems designed for ease of use.
You could try doing the following (close Access before going through these steps):
1. Navigate to each versions msaccess.exe on the machine and set the option to always “Run this program as administrator”. Once this option is set, be sure to leave it set.
a. To do this for Access 2003 you can navigate to "C:\Program Files (x86)\Microsoft Office\OFFICE11\MSACCESS.EXE" <or a path similar to this>
b. Right click on msaccess.exe and choose properties.
c. Click on the compatibility tab.
d. On the compatibility tab check the “Run this program as administrator option”.
e. After doing this, try opening your database again.
f. If it still fails, leave this compatibility option checked and then run a repair of Office 2003.
g. If it still fails, then open one of your problematic database, open the VBA window, click on the Tools menu and select References. Within the references dialog, please list what references are checked.
