Dora, When the download finishes, you should have saved a file on your system called SE2DDraft.exe. You have to run the executable to install the software. Follow the directions during the installation. The only thing you may want to specify different than the defaults is the default units. If you work in metric units, you can specify your working units to be metric on one of the dialogs that is presented during the installation. If the software installed properly, you can click on Start. There should be a an entry for Solid Edge 2D Drafting in the program list. Also, if you click on All Programs, you should see a program group called Solid Edge 2D Drafting V20. In that program group is two entries, Solid Edge 2D Drafting and Solid Edge Viewer. Also, look in the 'C:/Program Files. See if you have a folder there named 'Solid Edge 2D Drafting V20'. If there is not a folder there with that name, the installation was not successful. You can run the executable that you downloaded again to install the software. Regards, Rick B.
