And while it's probably safe to read the registry to see what drivers are installed, the documented say to get the list of drivers is: SQLGetInstalledDrivers archive.

I followed the idea posted above by creating a installer that will install the odbc driver first and then continue install mine. I'm afraid on tweaking with registry. Since odbc drivers are free I included it in the installer and install it if the system don't have odbc driver for sqlite.

Yes No. Thank you! Any more feedback? The more you tell us the more we can help. A device uses addresses in logical device address space. Each HAL uses map registers to translate a device or logical address to a physical address a location in physical RAM. For the device hardware, map registers perform the same function that the MDL and page table performs for the software drivers : they translate addresses to physical memory.
Because these address spaces are separately addressed, a driver cannot use a pointer in virtual address space to address a location in physical memory, and vice versa. The driver must first translate the virtual address to a physical address. Similarly, a device cannot use a logical address to directly access physical memory. The device must first translate the address. For example, most ISA DMA controllers, subordinate devices, and bus-master devices have insufficient address lines to access the full four-gigabyte system physical address space of a bit processor or the gigabyte system physical address of an x86 processor running in bit PAE mode.
By contrast, PCI DMA devices generally have more than enough address lines to access the full system physical address space in bit processors.
