Output of Library Loader 2.49

(copied with edits from forum post:
https://forum.winehq.org/viewtopic.php?f=2&t=35438&p=133676#p133676 where it
was suggested I submit as a bug report)

I have installed DesignSpark: (DS)
https://www.rs-online.com/designspark/pcb-software
and SamacSys Library Loader: https://componentsearchengine.com/tools

DS is now at version 10 and installed and working very nicely with wine-mono.
It was a real PITA to install when I did it using native deps, so I'm very
happy with that.
Library Loader is supposed to be able to launch and connect to DS when the
settings button is pressed. In normal use it opens component packages that you
download, adds them to the DS library and puts a symbol at your cursor ready to
place on the page.

When I was running these programs using native dependencies, it all worked well
most of the time, but I couldn't install the latest version (2.49) of Library
Loader. I was using 2.47, working ok.

I installed both programs in a fresh 32bit prefix. Library Loader installed the
newest version (2.49) - woo hoo!

BUT

I am getting an error from Library Loader when I download a new component or
when I click the settings button "Unable to launch/connect to Design Spark
PCB". Reverting all the way back to v2.28 and it works, much older that what I
was using previously.

It looks as though mono isn't doing something that it wants.
I have set: WINEDEBUG=mscoree WINE_MONO_TRACE=x
as per the forum post.

The log is from Library Loader 2.49, the newest version which installs with
mono but not with .net, but can't find DesignSpark. I launched the program and
pressed the "ECAD tool" (DesignSpark selected from list) settings button. The
point where the button is pressed is just after the cryptography stuff, where
it says "EXCEPTION handling: System.NotImplementedException: The method or
operation is not implemented." though this error is also present in the working
version, 2.28.
