You probably opened the file in the BIMvision 64 bit version. In total, there should not be a problem. However, since it occurred, I would like to ask you to send us a file that you tried to open. Please use email: firstname.lastname@example.org Of course, the file will be used by us only to identify the problem and find a solution. The file will not be shared outside.
I’m waiting for your reply 🙂
