EA App Error INST-14-1603

Whenever I try to install the EA launcher it gives me this "Inst-14-1603" error.

I spent many hours trying to fix because I just want to play the sims 4 and it keeps giving me the same error. and yes I have tried every fix EA tells me to do to fix these problems and it still doesn't work. this has only started after I got a new hard drive because  I was able to download and play the sims on my old hard drive but that ones too slow to even work now.

can someone please help me fix this in the comments.
