Try 2. Instead of a complete uninstall, I chose the repair option when I selected PS4 in Control Panel - Add/Delete. After repair I was still unable to open PS4, but was still able to open Disk Image Recorder.
Try 3. This time I did a complete uninstall, deleted the download file and chose to re-download from FTP Site 2. I closed down Internet Explorer, mail program, Anti-virus program and did a new install. I¡¦m still unable to open PS4, but am able to open Disk Image Recorder.
I ordered a custom computer a month ago (A-open) (2 DVD burners/w light scribe, 1GB ram, 150 GB internal h/d 150 GB removable h/d.) Roxio Easy Media Creator 9 installed at factory. Sad Story-
Could there be a possible conflict with Roxio and PictureShow 4?

Thanks for any advice you can send my way.
