This is a curious one. I was running a PC under Windows XP Pro SP2 but discovered that it had a corporate licence so over installed an OEM version which I had purchased. After this I could not run True Image because it came up with "E000101F4: Acronis True Image has not found any hard drives". The drives are certainly there in My Computer and for every other application. I also discovered the same message when trying to run PartitionExpert and Disk Director Suite. Tried uninstalling and re-installing True Image with no success. Any ideas please?
