You are attempting to use a Prepare for Image Capture task as part of a Job in Deployment Solution 7.6 to create a sysprepped Windows 10 image.
You are attempting to run a Create Disk Image with the Prepare using Sysprep option in Ghost Solution Suite 3.x to create a sysprepped Windows 10 image.
In Deployment Solution the Prepare for Image Capture task will show a status of "Waiting for the agent to get the task". On the client system, Sysprep will launch as a process but not finish. Once you end task on the Sysprep process in Task Manager it will log the error shown in the box below.
In Ghost Solution Suite 3.x the Create Disk Image job will fail with an error -99.
The setuperr.log, which is a log that Microsoft Sysprep creates when it runs and encounters an error, will contain the errors listed below. You can find the setuperr.log in the Windows\System32\Sysprep\Panther folder.
Microsoft Sysprep will not run on upgraded installations of Windows. A Windows 10 installation that was installed as an Upgrade from a prior version of Windows such as Windows 7 or 8.1 will not run Microsoft Sysprep.
Additionally, a Windows 10 installation that was installed clean and later updated to build 1511 is also considered an upgrade and Microsoft Sysprep will not run.
Please note that this is a limitation of Microsoft Sysprep and as such is not something that Symantec can fix or workaround. Please see the Microsoft Technet article linked below for information on Microsoft Sysprep including its limitations. The Limitations of Sysprep section in the article states "Sysprep must not be used on upgrade installation types. Run Sysprep only on clean installations".
In order to successfully run Microsoft Sysprep you must first install Windows cleanly.
