When i download any thing the computer always says that i have choosen the wrong disk what does this means?

Question

i dont know why when i download anything on my computer it refuses to install

Answer 1

Is your Windows operating system installed on the C: drive ?

Answer 2

This probably means your computer is sending the downloaded information to an incorrect drive.  Find out which drive your hard drive is installed in on your computer and make sure your internet browser is set to download into that drive.  Other than that, you could have a hardware problem (the hard drive might not be connected right, or could be malfunctioning).
