works for me many thanks
if you guys having trouble getting it to work
1: first before you install edit the host in etc folder under your c\windows\system32\drivers
2: be sure the internet is off then install
3: after install and opening it close all the wondershare running from task manager
4: turn off anti virus run the Run TC_Medecine.exe
"this is the reason why you cant save or export your video upon saving it requires to purchase or add watermark"
make sure edit the extraction folder to
C:\Users\%your pc name%\AppData\Local\Wondershare\Wondershare Filmora\11.6.3.639
remove %your pc name% on what ever your pc name mine was Administrator
and mine goes like this
C:\Users\Administrator\AppData\Local\Wondershare\Wondershare Filmora\11.6.3.639
ones extracted you must see a pop up saying another files already in that folder
just replace all and you can now save your video project.
