I was having this same problem, so I went and started looking for a solution. I had lost my disc, so I was looking for a back-uo of someone else's to use, since I still have my Key from it being on the website. I found a .rar file of it, and downloaded it. I extracted everything to my desktop, and kept on trying to get it to work, but to no avail. I had one last thing to try, and it worked. Go here and download the file that is given, and click the set up inside of the winrar file, instead of extracting it. I do not know why it worked, but it did, and now I have the HD PRO on my desktop again. Cheers!
