Skype heavily depends on Internet Explorer, even if you are using a different browser. Please compare the add-ons used by Internet Explorer in these 2 Windows accounts.
I don't believe I'm using any add-ons on this User account for IE. Though, whenever I used to start up skype I would never really get any of the windows or ads. It's like they were blocked. Maybe that has something to do with it?
Do you see them on the other account?
What about your Flash Player? What is the version installed on your computer?
Open in your Internet Explorer YouTube.com and try to play any video site.
Yes I see them on the other account. I've had flashplayer on this one as well and I just upgraded it to Flash Player 11 and downloaded IE 9. I can now see things when I start up Skype but it still closes due to the data execution prevention...
I think they real problem lies with the Date Execution Prevention. Something is triggering it to close skype. But what..
Kaspersky is a perfect candidate for Skype problems. Try to disable both antivirus and Firewall.
I just removed Kaspersky completely since my license ran out and I'm still getting the Data Execution Prevention...
