Hi Andrew, and thanks that took care of it!

I wasn't able to deal with it until the end of the working day due to a change of circumstances, but have just completed the fix early-evening with no problems.

I have opened a variety of song files from past and present just to check, and so far the missing Bass and all else seems fine.

Yes you were right, the old installation was to an external/USB drive (F:), and when running the sforzando.exe file installer it remembered the F: drive folder-structure address from previously and expected the location to be the same this time.

I pointed it to the correct C: drive location instead, and whilst the files it dropped there were of course already moved across from F:, it now also dropped a Registry Key sending things to the correct location on C: instead at last! smile

So now, as Meghan Trainor most profoundly remarked, It's All About That Bass ... again smile


NOTE
For the benefit of anyone searching the problem later and seeing this, there were a couple of adjustments along the way as my installations have all been via downloads with everything ultimately together in a /bb folder.

"hiq_instruments_sforzando.exe" should therefore be found among the downloads of anyone who has done the same not gone for the drive option with BIAB pre-installed.

For the same reason there is no "PG Music Inc" folder in C:\Program Files. Instead the "Band-in-a-Box Sounds" folder is in "bb/HiQ Instruments/" folder on whichever drive the user has chosen to use.

Thanks for spending the time yesterday chasing things down, I have learned a good few things about BIAB's workings just from following your knowledge and logic: those are the types of thing it comes in very handy to be aware of when you least expect it!
