If you created Capture Media CD to capture a reference machine, most probably you should execute it from Autorun. If you try to execute it from executable files within media, you will see it under processes but it will not initiate capture wizard.
But one another problem you may face is ‘handle is invalid’ error message.
If you have Symantec Endpoint Protection installed on reference computer and has client management protection enabled, by default it will not allow you to execute programs using AutoRun. Therefore Capture Media will throw “Handle is invalid error”.
To resolve, just disable this specific rule and execute it from scratch.
