New install directions

[myinfekted]

hi all,
I apologize if this is a dumb question but it's been so long since I've
dealt with software issues on the TI that I dont remember exactly what I
need to do. I have been using the TI as a VST with Windows XP and Cubase
SX3 for 6 years and it's been working perfectly. Now due to windows XP
support ending I decided to upgrade to Windows 8.1 and also upgrade to
Cubase 7. So basically I'm doing a new Virus TI installation on the PC and
on Cubase. I looked at the online manual for guidance but I don't think it was ever updated because it still talks about installing under Windows XP. Where are actual directions specific to Windows 8.1 and Cubase 7? Do I just need to download the latest TI OS version in 64 bit and will that take care of installing the Cubase VST end of it also? Or is that a separate download? Like I said I really don't remember if I had to set up busses, vst folder, etc when I installed the TI originally because it was about 6 years ago. Any help is appreciated. Thanks.
