WEBENCH-POWER-DESIGNER: WEBENCH® CAD/CAE Symbols BXL - error 87

Part Number: WEBENCH-POWER-DESIGNER
Other Parts Discussed in Thread: TPS55340

Dear All, I downloaded Cad symbols from the WEBENCH® CAD/CAE Symbols.

However, when I run this on Ultra Librarian 8.1, I receive LoadLibrary failed with error 87 (invalid parameters).

How can I solve this? Some specific designs such as

TPS55340_PWP_14.bxl

gives this error.

I'm running the Ultra Librarian 8.1 free version on my 64-bit Windows 10 laptop.
