Hi Armin, I see - that's called the "Template file".

The options dialog box won't let you enter in a value without a full path, but you can do it by editing the moi.ini file directly in a text editor like notepad.

Try this - open up the moi.ini file and edit the line for

[Settings]
Startup template=

And put your template file name in there without any path in front of it like this:

[Settings]
Startup template=default.3dm


Then copy that default.3dm file onto that USB drive in the same spot as moi.exe and it should probably get found when you launch the program, since a filename that has no path in it implicitly uses the program's current folder when the program tries to open it.

Does that do what you need?
