Export to Microsoft Excel requires the Microsoft Excel ODBC driver, which may not be installed on some x64 bit platforms
To add x64-bit ODBC support please download and install the Microsoft Access Database Engine 2010 Redistributable (or search for "AccessDatabaseEngine_x64.exe")
Nothing will appear to happen because all installation dialogs have been suppressed. Check Windows Programs to verify that the program has been installed successfully
Alternatively, you can use Copy as Text to copy table data from Synchro to paste into Excel, and Paste as Text to paste information copied from Excel into Synchro, but this has limited functionality compared with Export/Import from Excel
