First thing to do is make sure you have enough space on the C: drive to do the installation. You probably need at least 50-60 GB free.

I would make sure that the external USB drive is getting enough power. First, try a different USB port (maybe one on the back, instead of the front), or use the double plug provided with the drive (one provides the extra power, the other is for data transfer plus power), or hook it up to a powered USB hub.

Make sure you do NOT install to "C:\Program Files" (x86) or "C:\Program Files". This can cause problems on Windows 7.

Right click on the installation program button and from the popup menu, select "Run as Administrator".

If none of the above work, then I would try looking to see if there is something wrong with your computer. You might want to run a CHKDSK on the C: drive (you can Google and quickly find out how to do that).

If there are no problems there, make sure the external drive is not having any problems. Sometimes, the wires inside can get loose. When you received the drive, you should have gotten a little screwdriver with it. That's so you can remove the little screw and pull the drive out. Do so and make sure that all the wires are properly seated. Put it back together and try it again (and again, make sure the USB port has enough power).

That's where I would start to get things running.
