Right I have finally managed to get TI8 to create an Image and an incremental image while running Windows XP SP2 (Acronis Support haven't responded with any suggestions as yet - perhaps they're still busy ) To get it working under XP SP2 I did the following Uninstall TI8 Re-install TI8 Unplug a USB memory stick that was plugged in the machine So having done that I tried to do a full backup - it worked! Wonders will never cease! Then I immediately tried an incremental backup. That worked too! Dare I begin to hope? I then tried verifying the image. That worked too. So now I began to get over-confident and decided to try to explore the image. Nope! Nothing doing! Step by step I did Select Eplore Image and choose the backup file http://www.gus-walters.com/stuff/AcronisExploreImage1.jpg Select the latest Incremental backup http://www.gus-walters.com/stuff/AcronisExploreImage3.jpg Acronis chooses an unused Drive letter - H: http://www.gus-walters.com/stuff/AcronisExploreImage4.jpg Select proceed http://www.gus-walters.com/stuff/AcronisExploreImage5.jpg This clock is displayed for about a minute http://www.gus-walters.com/stuff/AcronisExploreImage6.jpg And then I get this error http://www.gus-walters.com/stuff/AcronisExploreImage0.jpg Now I have done a search on this forum and came up with a post recommending that you download the file http://www.acronis.com/files/support/SetupApiLog.zip unpack it and run in order to add the information to the Windows registry: - Delete the \Windows\setupapi.log file and reboot the computer I tried this and still no luck. Is this a feature that just doesn't work?
