How to get and install ADB Drivers for Sony Xperia S

I try to install ADB drivers for Sony Xperia S, but I cannot.
I tried to use one from here
http://forum.xda-developers.com/show....php?t=2635830

but each time I get this error message "DPInst.exe does not execute on your current Operating System". I have Windows 7 64bits.
Maybe somebody can help me with that problem?
