64 bit MS Access windows program via UniDAC

[tanghz]

Hi there,
As the title suggested, I can successfully compile a Win32 app using UniDAC connection+AccessUniProvider to open a Access database. When I change it to Platform Win64 bit, it could not connect. What shall I do? I guess need a 64-bit ODBC or sth?

Hello,

MS Windows doesn't allow to simultaneously install two versions of MS Access ODBC driver (x32 and x64), therefore, depending on the format of the appliacation (x32 or x64) you are developing, a corresponding client should be installed on your computer for the possibility to connect to a MS Access DB

thanks Alex,

Will the final .exe file including the MS ODBC driver? Or the user must install MS Access or ODBC driver at their own machine? thanks,

Hello,

No, you should either distribute the needed driver installer with your application, or users have to download and install the driver by themselves
