Once you have managed to download the nine files and install it you want have to install any other extra stuff. (I downloaded the full version or
one big file)
Read the installation manual before you do anything:

If you cannot open the manual you wanna install 'Adobe Acrobat Reader DC' from here:
www.get.adobe.com/reader (uncheck the two boxes for 'McAfee Security Scan Plus' and 'True Key™ by Intel Security' before you click on the yellow 'install now' button)
Keep in mind that silent hunter 3 is quite old software at this point and that an easy installation process is at this point because of that, sadly, not guaranteed.
