SAP 7.7 Compatibility with Microsoft Access

Hello,

I have an application running on Microsoft Access 2007 and working fine with SAP 7.4. When i installed the SAP 7.7 version, the application give me a runtime error and then shuts-down. When i try to open the Designer Interface, it is also blocked.

This issue doesn't show in SAP 7.4
