Not sure if this is in the right part of the forums? but here we go. I am formating and reinstalling windows 7. I have a Dell Inspiron 1720 laptop. Intel 2.3 ghz duel core, cpu. upgraded to 4 gig of ram. done months ago. New 750 gig HDD. New to this install. just bought it. Installed with a dell windows 7 disk. It activated fine. had a few problem with the install. could not install Windows 7 usb dvd tool could not install Office 2010. Did get NOD 32 install and all the windows updates. I figured there was aglitch in the install. I formated and reinstalled windows 7 from a usb drive i created on another computer. that i just installed the windows 7 usb dvd tool on. windows loaded fine, so first thing i tried to install the windows 7 usb dvd tool would not install. so formated and started again. All went well windows 7 activated fine. tried to install the windows 7 usb dvd tool again no joy. so I went ahead and installed all the updates. NOD 32. windows office all went well. tried again to install the Win 7 usb dvd tool no joy. I have googled the problem there is no info out there on this problem. I searched the problem in this forum nothing. I had this tool running on the original install before i started this whole thing and it worked fine. Any suggestion would be great! Nothing invested but time!
