Thanks OB, but I don't have SD2. I think a few may have misunderstood me. On my old system, I had Sonar 5 through to 8.5 on it. Each time I bought Sonar, I always bought a full version. When 8.5 came out, it was way cheaper to buy the upgrade than it was to buy the full version. So I got the update, which stated it needed 8.0 installed in order for 8.5 to install.
Now, all the stuff above was on another machine that completely fried 3 weeks ago. This leaves me with install discs of Sonar's full version from Sonar 5 to Sonar 8. I don't want any of them on my new pc....all I want is Sonar 8.5. When the new machine I have here now was being built, I asked the DAW builder if he could put Sonar 8.5 on it for me using my codes that I have, to which we said "sure no problem".
Now all I want to do here is install SD3, but for me to use my upgrade install of 8.5, it needs Sonar 8 to be installed first. So I have no session Drummer 2 or 3 right now. SD 3 WAS installed on this new machine, but for some reason, I do not believe the .dll's are registered properly or something as they DO exist. See what my problem is now? :) Thanks for the suggestion though.
