Hello
I know this Topic ist not a new one, but the provided solutions didn't work.

I put my application to a PC (Win7). This application is using mySQL with the driver for direct access. So I put the file dbexpmda40.dll to the folder C:\Windows\System32.

When I try to connect to the database it appears a error message: Unable to load dbexpmda40.dll (ErrorCode 193). It may be missing from the system path.

what can be wrong else?

Thank you

Hello,

If you are using Windows 7 64-bit, you should place the dbexpmda40.dll library to the C:\Windows\SysWOW64 directory (it is a directory for 32-bit libraries).

I'm using 32 bit, what means the error code 193?

This error means that you are trying to work with the 64-bit dbexpmda40.dll library. To solve the problem, you should copy the %dbExpress_driver_for_MySQL_Install_Dir%\Bin\Win32\dbexpmda40.dll library to C:\Windows\System32 .
