I bought a Lenovo labtop off Ebay. Shockingly, recieved it with a full HD and Win7 Ultimate 32 bit. I would like to do a clean install with Digitalriver's X17-24395 iso image. The computer's OS has X15-3892 part no.. I believe Digitalriver is of FPP flavor and the lenovo has R retail in its propeties. Both are 7601 build. Can I use the X15 productkey to activate the x17 image, will it activate online without loaders?
