You would need to contact our Support Desk and send them the logs for us to be able to troubleshoot what could be going on here. With that said some USB Drives and ports can function slower and cause issues with the DISM process to mount and modify the WinPE Boot WIM file. Sometimes using a different USB Drive and or port can resolve those types of issues. With the "/iso" switch failing on the DVD Restore Architect we would need the logs to begin to look into that issue as there could be a number of different problems causing that result. We are currently working on created more detailed Hyper V and Virtual Machine documentation to assist customers with some of the common issues that we have run into using VMs. If you can contact our Support Desk and send us the logs form the system that you are seeing the issue on we would be happy to see what else we can do to help address this issue with you. It could also help to make sure you do not have Antivirus software installed on the system you are attempting to create the USB or ISO from, as there are known issues with some AV software and DISM.

Hey Guys -  I'm new to ImageAssist and working on using it for our company.  I'm building my base on a Hyper-V Cluster so creating a bootable ISO is a much better solution than a bootable USB drive for me.  The problem is, I am getting an error when trying to create either. I downloaded, extracted, & installed the latest ImageAssist onto an E6440  laptop with a fresh installation of Windows 7 x64 Enterprise on it and all drivers installed.  I launched ImageAssist, then went to create the bootable USB drive.  With a drive inserted, I select it from the list, choose NTFS (get same error with FAT), and create media. I confirm the action to begin drive creation and files start to copy.  A few minutes later, it seems to finish and a dialog box appears stating "Creating USB Drive...Mounting ImageAssist Environment/// Failed.  Despite the message, the drive seems to at least partially work as I can boot to it. When trying to create an ISO by running DVD_Restore_Archetect.exe /iso from a command line, I get the same exact message.  In the log window, it says that an ISO named C:\Dell....iso has been created, yet there are no ISO files in the root when finished / I get the error. Any idea what's causing this to occur?  Thanks!
