MSP432P401R: cad file

Hello,
There are three packages for this device. LQFP, NFBGA, and VQFN. Which device are you trying to open via the Ultra Librarian?

Update:  I ran the LQFP package and was able to build the PCB and Sch files.  The readme.txt file generated from Ultra Librarian provides a link to a youtube video which you might find helpful.

1. After running the Ultra Librarian export for the first time,
you will need to copy the following files into an area where
they can be accessed for all future translations. They are script
files that Altium will need to be able to find.
a. UL_Form.dfm
b. UL_Form.pas
c. UL_Import.pas
d. UL_Import.prjScr

2. The above script file will need to be run from within Altium.
This can be done by going to File, Open and selecting the
UL_Import.PrjScr file stored above.

3. Select the UL_Form.pas file form the new project that has loaded,
and then select runfrom the drop down menu. You will need to select
the form again. Run the form.

3. When the script is run, it will ask you for the file name of the
Ultra Librarian file to run. You should select the latest file
produced with a date code (for instance 2010-02-17_23-12-34.txt).

4. The script will open a new Integraged Library project and import
the Ultra Librarian data into it. When complete a message box
will pop up saying that import is done.
