2) Uninstall Java
It didn't work for me
I tried this way with some of your Shimeji, but they still don't work; I still get the message "failed to load conf. See log for more information"
None of your Shimejis work to me, not even with this method. The only one of your Shimejis that work in my computer was the nsfw animaloid female/male Sylveon; apart for them, not a single one
Thanks for the reply (and sorry for the delay, I have no Internet, I use wifi).
I already realized what was the problem:
The only difference of that specific version of the Sylveon Shimeji (NSFW- Animaloid Male/Female) is that it have no sound files (the "700 - Sylveon.wav" file of the other versions); and that's it.
My PC have no sound card, so it have no audio output. Java obligatory requires an audio output if the .jar file includes any sound; that's why they doesn't work in my PC
