Problems with Launching Virtualwind
Virtualwind Does not Launch
Very occasionally, nothing at all happens when you Launch Virtualwind: no messages are displayed, no errors appear – it looks like nothing at all happens. It is unknown exactly why this happens, but it seems as if SketchUp "forgets" to issue the call. If this does happens, just try it again. This will almost always make SketchUp issue the call to Launch Virtualwind. A side-effect of this is that it can make SketchUp "remember" to issue the first call – so suddenly two copies of Virtualwind open. Just close one or the other.
Virtualwind Launches Empty
It is most probable that you have accidentally generated an empty VWS file. See the Problems with Exporting troubleshooting section for some explanations and remedies.
If you are sure that the file is not empty (for example, if you looked up file in My Computer and saw that its size is greater than 1KB), check that the filename does not contain any foreign (non-ASCII) characters: Virtualwind has problems loading files with names that contain non-ASCII characters. If the file does contain foreign characters, change the name so that it does not. It is best to perform a full export.
