Puzzle - I have created a fresh VistaPE disk for Acronis 11 (got plugin) - simply so I could try out ATI 11 - varying results - one machine doesn't show Total Progress when backing up or Operation in Progress % well it does but it's 0%. The newer machine does show everything but trying a recovery from within Windows from external USB the Acronis Loader cannot seem to see the drives and reboots back into Windows, (can see drive using a boot disk) whilst the Dell doesn't seem happy at all with TI 11. Anyway now to the puzzle - when I load the PE disk it works fine except for Acronis. When I click on Acronis I get a message saying that the serial number is incorrect or not recognised and to reinstall Acronis. I have to put two serial numbers into Acronis 11 when installing - my new serial key and then my old one for TI 10. Is it this that has confused Winbuilder? I am completely stumped as to what the issue is or how to get around it. Anyone come across this before and if so how did you solve it?
