When running a User Driven Installation (UDI) Task Sequence on an x64 (64-bit or AMD64) Windows 7 machine, it shows the following warning under User Data and Settings:
No valid Windows directory found, data and settings will not be captured
This can occur when your 64-bit image is configured as a 32-bit image in the UDI Wizard Designer. When you add your image, the UDI Wizard Designer defaults to specifying a Windows 7 x86 (32-bit) image:
If using a 64-bit image you will need to change this to AMD64.
Once you remove the x86 reference and added it back as AMD64 in the wizard it allows the Task Sequence to work as expected.
