I'm a new LFS guy.

I saw that LFS was registered on Simhub, so I tried to run it, but...

The message that I saw is 'Is LFS correctly installed on a hard drive?'

However, LFS feels shunned not only by Simhub but also by most similar software.

I have sent an email to Simhub, but there is no reply, so I guess that LFS is a game that is ignored by them.

I think LFS should improve this, not Simhub, but would it be right? ^^

What's there for LFS to improve? LFS has its data exposed. If Simhub is trying to run LFS incorrectly that's up to SimHub to fix.

The error message suggests it's trying to exec LFS.exe without setting the current directory to be the LFS directory which will cause issues as LFS won't load assets properly.

I have the same problem. it used to work before. but now simhub doesn't find the exe although the path is correct.
someone an idea?

Yes, set outGauge ID to 1. Delay should be set to 10-15ms, because simhub can't run faster than 60Hz anyway, that's in a paid mode, free is only 10Hz. You can completely disable the outSim because simhub doesn't read any data from it, it only uses dash data from outGauge.
