I downloaded the adksetup.exe file from your link in an earlier post above.
Since then I have uninstalled the ADK and relocated the ADK files (Windows Kits) to the C: drive instead.
So the path I browse to is now
C:\Program Files\Windows Kits\8.0\Assessment and Deployment Kit\Windows Preinstallation Environment\x86
Alas I still get the message "The specified location does not appear..."
Can you confirm for me the above path is correct? I ask this because I noticed the DISM and imagex tools are elsewhere.
Is there a file I can locate in the above path that would tell you I am using the correct ADK when identifying that file's propeties? i.e. the DISM file is at version 6.2.9200.16384
