ADO connect work in win32 but not in x64

Question

5.00/5 (1 vote)

See more:

We use DAO to read database in C++.
When we compile and run the application in 32 bit (on a Win7 64 bit machine) it works well.
When we compile and it in x64, the connect fail:
The connection string is simple:

"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\db.accdb"

the database in a simple MS Access 2007 file.
We saw a lot of people saying that the solution is to use 32 bit, but that is not an option for us...
Did anybody solve this problem?

Thanks!

Tried to install it already, but this is for office 2010, and it does not allow me to install it unless I remove all of the office 2007 first... and we don't even have office 2010....
