I have just completed a hard drive format and reinstall of os (Windows XP Home). Have installed al new drivers in the sequence recommended by Dell (the computer is a Dell Optiplex). Have updated Windows with Service Pack 3. When I try to install the software for my mobile phone (samsung blackjack II) I get the following error: Setup exe has encountered a problem and needs to close. Sorry for the inconvenience and the option to send or not to send to Microsoft. I went through all of this yesterday; and at the suggestion of a pro support tech from Dell repeated the OS reinstall. This time I tried installing the phone software before any other - still the same error. I have verified the drive; the disk (it will install on another pc) and simply don't know what else to try. Any suggestions would be most appreciated.
