I recently bought Dell Inspiron 15 5547 with Ubantu.

When I installed Windows 7, I receive error message "Synaptics TouchPad 64-bit Enhancements has stopped working." Wen I close this my touchpad start working erratically. While typing cursor moves itself without touch or click.

The driver given on Dell site under Windows 7 is same as for Windows 8. I also tried drivers from Synaptics website but nothing worked. Can any body suggest the solution?
