Hi,
I would like to connect to a SQL Compact 4 database using dbexpress driver in Delphi XE4.
When I try to open the connection this error occours:
'The database file cannot be open with the current version of SQL Server Compact Edition'.

If I use your test.sdf database all works.
The problem occours also if I open the connection in Delphi IDE. I think used driver is 3.5, bu I need version 4.
How can I open a version 4 sdf database from Ide and at runtime?

Thank you.

Hello,
thank you for your suggestion. It works great.
