I'm sorry, but it won't be solved by the way you told me. Error codes B03 and A04 keep coming up. I still need help.

Hello, I purchased FREDO6 BUNDLE 2022-8 PACK. I received the license and extension files, but I got an error code ( ERROR_A04 ) in the license registration process.

FYI, I'm using the Sketchup 2022 program, the SketchUcation version is 4.3.1, and the Fredo6 LibFredo6 version is 14.2.
I also converted computer user name to English name, but it won't be solved.

What kind of solution is there? I want a quick solution.
I'll be waiting for your answer.
