I hope that I didn't just mess myself up and lose $151.00. While waiting... and waiting... waiting for my new MacBook Pro, I decided to order VM Fusion and Windows XP to install on it when it arrives. I know NOTHING about Windows. I got VM Fusion from Apple. But, I kept running into problems ordering Windows XP. I didn't know which "version" to order. I kept finding versions which said "upgrade." I'm not upgrading from an older Windows OS. So, I figured that one would not work for me. Then, I kept running into a problem with retailers saying they do not have any Windows XP software available, because Microsoft does not distribute it anymore. I finally found it available at Tiger Direct and ordered it for $149 plus shipping. Well, it came and it says OEM version (NOT returnable for ANY reason.) What does that mean? Will it work for me? All I need it for is to enable me to use IE 7 on my Mac, as so many sites will not allow Macs to access them.
