I'm really a beginner in this, sorry for that. Guru, Thanks for the information and for noticing the fact that there was an error in my email address, it should work now. I will try Audacity when I have some more time, work you know! Alrobin, Surprise, surprise, I just checked my installation again and guess what. Yes, if I press the "?" button I see also the long message you mentioned. I had no change to see if the presentation is running well, so I don't know yet. I think that the reason is because the difference between 4.20 BETA and the real 4.20 version of pictures to exe. Yesterday I did an upgrade to the final 4.20 version and tried to run my presentation without completely booting my system, probably this caused al my troubles. I hope it will work now. But just in case Alrobin, what do you mean with the .pte file ? Is this the executable ? Thanks for all the help I have received from you all and sorry again for the trouble, Rudy
