DISMUI was already supporting the new version of Windows Embedded Standard 8 CTP3.
DISMUI has been updated to fix some issues when installing Feature Packages in Offline Mode.
For bigger packages there was a need to create a scratch directory. DISMUI 188.8.131.52 is now creating a temporary scratch directory to solve the issue. This directory will be removed afterwards.
The new version introduces a new feature to display all the dependencies of a selected Feature Package. This will help you to find out why certain components are pulled into the image.
