Thanks Scott. After reading the upgrade docs, which it finally occurred to me I could do before installing the 32 bit version, duh, I was sure enough that it would act like that to go ahead, and it did. All sorted. Sometimes what you actually have ot *do* is simple, but uncertainty and not wanting to make a mess slows you down. OTOH, sometimes you just plow ahead, and something stupid happens. (Like having all the NI Komplete dlls at the root level of /Program Files/VSTPlugins, instead of inside an NI folder. Which doesn’t hurt anything, I just don’t like it, and wouldn’t have done it that way if I’d known what the installer was going to do given the settings I told it.) Thanks again, Dave
