New hard drive and no joy

I had to have a new hard drive installed and my FSX and 2004 installed no problem then when I tried to install P3d and FSX steam no joy. I tried to install using administrator still no joy. I am wanting to install on my E drive that where the other 2 are. Has anyone had this problem before? Any help much appreciated. I am elderly and not too computer savvy!!!! I had 3-4 hundred planes installed and will have to reinstall that but at my age that will keep me out of trouble for a while. I have written Dovetail and P3d so far no response!!!! Thanks for your help. homeboy
