Currently I have a 32-bit version of Windows 8 Professional, but it's not compatible with the program I need to install. There is no available 32-bit version of the program/ The program requires 64 Bit Version of Windows 7 or 8. I have 64 gigabytes of hard disk space available on the primary, but I also have 739 gigabytes free on my secondary Seagate Hybrid SSD. This is the hard drive I plan to use because of all the free disk space I have available. I want to use this new hard drive because it's fairly new and it's SSD. My plan is to partition this drive so that I can set the amount of space I want for the new OS and programs .I don't want to compromise any of my currently installed apps on the 32-bit version of Windows I have by upgrading it to 64 bit OS or am I wrong? This is why Im not sure to just start fresh or upgrade. What am I to do?
