Hello:
If you download the demo version of Combustion from www.discreet .com website, then you should be aware that the TUTORIAL files are NOT included (this saves space and download time. ) You must download those tutorials seperately later.
The Demo CD-ROM does has the full tutorial files, and after you install the demo program you should be able to Browse your computer and find them, and just 2x the CWS file to open it..... The tutorials are normally located at:
X:programdiscreetcombustiontutorials
If a Tutorial CWS can NOT open, then it may be corrupt .... try to reload the file....
Best of Luck.
regards,
JACK
