What isn't working is when I try to run this process as a windows service. The python is running properly but kicking off LTspice results in this error code 3221226505 so I get an email saying "Simulation failed with status code 3221226505".
Presumably that is a Windows status code.? I think it did not come from LTspice, but it might mean Windows is telling you that LTspice did not exit happily.

Can you find what that error code means, if it's from Windows?

It's curious that the message states "Simulation failed ...".? Where did that word "Simulation" come from?

Did LTspice create a .LOG file?? What does it say?

Since there is no descriptive error message I have no idea why everything works fine when I run it while I'm logged in but it won't run as a background service. I need it to run as a background service because the server won't let a user stay logged in indefinitely.
I am unfamiliar with running programs in a Windows background service.? Is it possible that a background service does not "see" itself with a normal default directory?? Is it a mirror of the right directory, including all contents?? What about its environment variables?? Does it see the LTspice .ini file too?

I'm assuming that everything works now that you moved all the symbols (and models too?) into the same folder with the schematic, when run normally.? I think that is what you said.
