I properly upgrade my revit 2015 to revit lt 2019. hereafter,When I opened the Arch'l. Model, I found out arch'l .rvt model was on the link list at the same filename, but it was Not loaded
open manage link and try to remove
After I upgraded it to Revit LT 2019, I tried to re-load from that model link, and it was not able to re-load, because it was opened in a same file name.
try to reload again.
