When trying to install, requires activation code from the beginning, anyone else having this..? or a bypass? Thank you in advance.

Found this elsewhere:

turn off the Internet
simply create and rename the folder in Lumion on the c disk and move all the files to this folder,
open cmd
and enter:
C: \ Lumion \ Lumion_2023_4_2_Download.exe -s

after installation is completed:

don't run lumion
turn off the antivirus and copy the crack (lpro2023420-zmco.exe) to the lumion folder (C: \ Program Files \ Lumion 2023)
