I just installed windows 10 on my computer, and I think I must have to reinstall farmworks but I'm not sure. When I open program files I can not get farmworks to open. It shows I have all of the program files, a farmporj folder, and all of that. I did back my project up on an external hard drive before I did the install. When I go to local Disk, farmproj and scroll down to office, it says It can not open because cw3230.DLL is missing. Do I need to download farmwoks software from the internet again? where can I find product keys and or registration numbers? I'm not sure what version I had last either, but I think it was 2013.??
