I've been getting the error regarding Xenocode (whatever that is...), I "okay" the error and Fusion launches. This only appears once during the session. If I reboot, I'll see the error the first time I launch Fusion. Anyone else getting this error?
More than likely its some Vista 64 bit issue.
Xenocode is the underlying technology that allows the all-in-one-no-install version of Inventor Fusion. It pages all of the files, registry entries, etc. into that one EXE that you downloaded from Labs. This piece must be encountering an unexpected condition on your system. Can you tell me more about your operating system and what other programs are installed on your computer?
