To install SoftCopy under Windows 8, you first have to configure it to accept test-signed drivers.
Launch the command prompt in Administrator mode. Move the mouse cursor to the top-right corner of the screen to bring up the charm bar. Then click on the "Search" button.
Type "cmd" into the search box. This will bring up the "Command Prompt" icon on the left.
Right-click on the "Command Prompt" icon. This will bring up a list of additional functions at the bottom of the screen. Click on "Run as administrator".
Now you should see the "User Access Control" warning. Click on "Yes" to continue. This will launch the command prompt in Administrator mode.
In the command prompt, type bcdedit -set testsigning on and press [Enter].
Once the command executes successfully, reboot your machine for the setting to take effect. You can run the installer to complete the installation of SoftCopy.
Once SoftCopy is installed successfully, you can turn test-signing off by following the above steps again and entering bcdedit -set testsigning off at the administrative command prompt, then reboot the machine.
