Hello,

1. I would suggest "Merge", if you are copying the folders from another location. (I assume that's what you are doing, since an installer wouldn't ask you if you want to merge, it does that automatically). The folders may very well already exist but are lacking the video files, since Video RealTracks add videos for some existing RealTracks instruments

2. It sounds like you don't have the VJT tool installed (which is included with Video RealTracks). I will private message about this since it is specific to your account.

3. The Video saving is currently unavailable in Band-in-a-Box x64. For saving a video, you'll have to launch the Band-in-a-Box-32bit app (this is temporary, and we'll have a free patch to address this issue)
