My 2016 draftsight was working fine yesterday and now will not boot. All it says is that there is a problem with the software and it needs to close. System restore is out since there does not seem to be any usable restore points. It looks like im going to have to remove and reinstall. Does anyone know what folder all of you customization lives in so I can make a copy of it before I remove.  l  can then just  replace after the new install so I don't have to sit and re do all my toolbars and custom settings. Thanks in advance
