I have Macrium Reflect free version loaded on three machines. I have encountered a problem with one of them. It won't open the backup files! I took the hard drive to another machine to make sure that the backup files are secure. Macrium won't let me open it on a different machine. That is also true of the other backup drives. They all say access denied when the drive is hooked to a different machine. How do I get those Macrium folders open when not on the machine that created them?
