Maybe a dumb question but as I read thru this forum I can see that nothing is as simple as it appears to be. I've d/l trueimage7.0.638_s_en some months ago and obtained the registration via Acronis, a special offer. About 10 days ago I purchased V10 upgrade (again from Acronis site) and received the registration number & link before I d/l TrueImage10.0_s_en. Neither of the two yet installed or used. Any special procedure or tips before I get it wrong? I'm on XP Pro. Hard drive space no problem and I'm using various partitions but have a large spare partition to play with. My intention is to write/image to an Iomega USB drive. Any suggestions, regarding installation, most welcome.
