Using 5.7 and having issues with the resulting HTML file generated. Not well formatted and lots of garbage characters.  Also, PurePlayer.jar not included in the download.  The .ivp is created OK because I got this to work on my 5.5 version html file etc.  I may be missing something in th 5.7 install.  
 
Also - was there not some way to export to FLASH?

Dear sir,
yes the .jar java applet is no more provided with the software since 5.7. You have to download it from the www.immervision.com website.
 
The Flash export should work fine. You have to select the first choice in the publish formats: Flash_White_Big.html and render a .ivp.
