Hello bobbiepc,

You need to determine the main issue first, if the computer is unable to download and install a program then something is really wrong. I would start off by checking if the computer has any free space, then running an antivirus scan. Alternatively you could initiate a reset of the operating system and that should fix things. Once you have the program installed check to see if you are experiencing the same issues regarding color.

Free Antivirus, Free Anti Malware.
