There is a conflict with the database driver, on Windows 7 (64 bit), between Microsoft Office 2010 and  Advance Design 2011 (64 bits).

This problem is reflected in the fact that after installing AD2011 on a computer that has Office 2010 32 bits, a message requesting the installation of a component is displayed each time you start Word, Excel, PPT ...

The solution is to update the "Access" databse driver. To do this, simply download the patch from the following link: ftp://ftp.graitec.ro/Helpdesk/accessdatabaseengine2010Sp1.zip.

Another solution is to install the 64 bits version of Office 2010.
