I built a computer several years ago that, by today's standards, isn't very powerful. I installed a 32 bit copy of Windows 8 on it and my computer had trouble handling it. So I built a new computer with an i7 processor and 8 gb of RAM but used the same harddrives. Now I'd like to upgrade it too the 64 bit version of Windows 8 using the DVD that came with my copy. However, when I try the only thing I get is a "Read Me" document that says "This disc contains a "UDF" file system and requires an operating system that supports the ISO-13346 "UDF" file system specification." How do I install my 64bit copy of Windows 8 without having to buy a new copy of Windows 8?
I upgraded my win 7 to win 8 pro on a 32 bit laptop. I selected the DVD option rather than direct download of ISO files. I recieved both 32 bit and 64 bit versions in two seperate DVDs from MS. My problem is the product key they provided works only with the 32 bit version. Do I have to buy a seperate key to use with 64 bit win 8 pro? I will only be using this key on one computer.
