Since nobody helps, I've found temporary workaround by myself: i installed Realtek driver from RAMPAGE V EXTREME (on my M7Hero; may work on another Z97 boards as well) and Sonic Studio doesnt crash anymore! Also, Asus Sonic Suite Plugins must be installed (you can see it using IOBIT Uninstaller) as well as the "C:\ProgramData\Package Cache\{928023c5-f0b7-4152-bbeb-8d74bc130782}\SetupSonicPlugins_R2.exe" must be there, otherwise it will crash (the key can differ).
P.S. I know that my english sucks, but i hope this can be helpful for somebody...
