I pull up the Command Prompt; it's another black box with white text that kinda looks like MSDOS and I type "fciv.exe." Nothing happens; it says "fciv.exe is not recognized as an internal or external command, operable program or batch file."
You have to navigate to the correct folder/directory first. Your prompt probably appears as C:\Users\username>. You will to use the 'cd' command.
Typing "cd" doesn't do anything either; I type "cd", hit enter and the same C:\Users\username> appears right below it.
I really cannot buy any extra equipment or hardware for this. Right now, I can only afford to invest like $30 or $40 USD into this, and ideally, I would like this to be all in Bitcoin; buying any gear would wipe out any money for Bitcoin thereafter.
OK, if you want to get into Bitcoin now, can you afford to lose that $30-40? Why not start with a simple wallet and only $3-4 dollars, that way if you lose it no serious damage is done. As you gain in experience you will find things that seem horrendously complicated now become clearer.
Yeah, it's just that others have suggested I get another, dedicated computer for this, and the printer he suggested is $200 USD. All I'm saying is that I can't afford to buy new hardware for this; not yet atleast.
Do you have antivirus software installed? Do you have a two-way firewall installed? If not then consider your computer as insecure and don't use it for anything important or valuable. If you don't know then consider it insecure.
Good, free, easy to use software packages are AVG anti-virus and ZoneAlarm firewall. Other products are available.
My trial Norton Antivirus expired a few weeks ago; I just removed it today and started using Windows Defender. I ran a full computer scan and it said my computers safe. I don't know if they have/had "two way firewall" functions. I'll look into those other services you suggested.
