I've installed build 4560 which has the image tool. And I have deleted the one snapshot that I made from my hard disk image (and so have none left for this drive). But when I select the disk in image tool to try to expand it I get the message:
Image Tool is unable to process the file. The format of the hard disk image you selected is not supported in the current version. If the disk is used by one or more virtual machines that have snapshots, delete all the snapshots for these virtual amchines using Snapshot Manager and try again.
Is there something else I should be doing? I though Image Tool was supposed to work with this latest build.
