Hey there @User-8e6bd8f625! Welcome to the community! So this is a memory error, is this occuring during installation or during your first launch? The rest of the error would also help as well, if you can retrieve the stack trace (the first couple of lines after the memory error) we may be able to see what’s causing the hold up.
Many times when the engine fails to install for a memory issue it can be down to permissions. Did the user access control window appear when you went to install?
