I got that solved.
and Softwares of SR220J,
I installed Sony Event Service from Windows 7 Ultimate 7 32 bit, which is my version, then the rest of the drivers and utilities from Windows Vista 32 bit.
I think drivers from Windows 7 is primarily made for computers that are already set to them when they were released, so if you upgraded from Vista to 7, drivers should be downloaded from the Vista version.
Hope it works on your computer too.
