While we wait for Noel to post instructions with pics on how to open ST (pics always better than words) yes, I have seen that thread but I just assumed most folks ran everything as admin - I don't run my PC's any other way.
Not being admin causes way too many of these strange kinds of problems (can't write this or that, can't run this or that, and the not so hidden and sometimes not obvious results of this are programs that hang up, you get errors, crashes, lose work, …)
Life is too short to let MS, or the other "my way or highway" lemmings at "Appleway" think for me or try and be police for me.
there were similar issues last year (with first HI-Q set) but they were all fixed IIRC in simply moving the \Band-in-a-Box\ folder up, down or over one level (I don't remember) - this year seems a lot more "involved" for some reason
Another thread from last year
http://www.pgmusic.com/forums/ubbthreads.php?ubb=showflat&Number=200806Sums up nicely where/how these multiple ST files work (at least for me and the poster from last year) that's why when even Mac has issues with this, he's no novice on PC's, DAWS, PC sound, or BIAB I'm a little suspicious on where fault actually lies. That is, while it might be simple fix it might nto be an obvious one.
