This may be mainly due to the following two reasons:
When the soundtrack can be heard but no image appears, your graphics card does not sufficiently support 3D hardware rendering.
Solution: Try to play the EXE presentation on a different computer. See also Graphics card.
If neither an image is displayed nor the sound track is audible, the computer has no sound card or there is no appropriate driver for the sound card installed.
Solution: Check sound card and its driver and install it, if necessary. Alternatively, try to play the EXE presentation on a different computer.
If the monitor goes dark for a short time after the start, following which Windows reappears, you project may still contain data objects for screen field control from an earlier Wings Vioso RX version.
Solution: Remove all data objects for screen field control from the universal tracks. The links to the screen fields were removed while the show was loaded. But for EXE presentations the timeline must not contain any data objects for screen field control.
