My tip. Install Cubase in a Fresh Windows install with minimum junk!..no ifs, no buts …it is the best way to Cubase happiness…then see where the journey takes you. Over the last 15 yrs or so, I have accumulated nigh on 170 VST plug ins that I “have” to install…( I count NI Komplete for example as 1 plug btw)…So I have a tad more experience in only debugging most of the “Extra” stuff one needs to cram into a windoze workstation…and By jeZuZ…problems come from so many areas when installing ANYTHING extra that it could make a sane man mad, but it can be stable, it can be solid…you have to decide just how important it is to get it there…I always find just overwriting “stuff” is a surefire way to a destined reformat! Even the order,in which things are installed can have a bearing on the outcome, and that includes the order of installing your basic Motherboard & Chipset drivers,Gfx drivers, (which versions work better than others) Sata drivers, firewire card drivers, all of it matters in getting it right,and keeping it clean. because so many bits of software are dependant on what is ALREADY installed on your pc, C++ redistributables for example, (at the current time of looking I have (installed by plugins & vsts , 6 different Redistributable packages!!)…and even more so, what ISNT installed can have a bigger bearing on the way things run.
When I updated from 6.03 to 6.04 .as usual a Fresh complete reformat was carried out,with absolutely NO remnants of a previous Cubase install. everything was “redone” from scratch…win 7,sp1, everything …Including rebuilding Mediabay, and freshly retagging over 2 terabyte of samples…why you ask…because I need Cubase to be stable, & thats the best way to keep (my pc) it that way. It takes about 4 days for a fresh install for me,
I find its worth it, Some others here wouldnt/dont…but they usually do after the learning curve & pain they receive!
