Oh man...I had the same thing when I installed Windows 7 way back then!!! Do u have a driver
called Sony Utilities...I think u'll need to install that...either way..it was one of the following drivers
that got it working for me....But my machine is a bit old (2007 model) so it may not be available on yours
1) Sony Utilities
2) Sony Shared Library
3)Vaio Event Service
I know it may not be much but just thought I let in my two cents!
Also do a google search chances are someone who got it running wrote down some info. Thanks how I got it going. Gd luck
