I suddenly cannot use Bandlab assistant anymore, either.
I read all of their suggestions:
erased all copies, even in temp dir's, reload newest file, failed again; I even did all of their recommended software fixes, to no avail.
everytime i reload it, the new install freezes at one-third progress and sits forever.
I've even repaired (Microsoft C++ Redistributable 2015/2017) . no good either.
rebooting each time as well.
I've been using Cakewalk, since the 90's ...... I'm not kidding.
I've used Sonar for years, Cakewalk, 9, as well. I can still use Music Creator 6.0.
I'm ticked off now!
Riles !
