Discord Bot Java (Maven) Library not found, loading failed (com.sedmelluq / lavaplayer)

I programmed a Discord bot with Java (Eclipse). If I start it via console in Eclipse, it works without problems. If I export it as a "Runnable JAR file" and start it with the start.bat file, it also works fine.

start.bat:

java -jar NameOfTheFile.jar
pause

However, I don't want to keep my computer switched on permanently. A friend would have no problem with this, so the bot runs on his computer. If the bot is started by the start.bat file, there is no error message and it works. However, if music is to be played (triggered via the bot in a voice channel by !play ), the error occurs that the library (needed to play the music) was not found ...

I have Windows 10 + openjdk version "11.0.7" 2020-04-14
the friend's PC has Windows 7 + latest Java version

The error (short version):

I can attach the pom.xml if necessary. com.sedmelluq or lavaplayer is added by the following depency:

<dependency>
  <groupId>com.sedmelluq</groupId>
  <artifactId>lavaplayer</artifactId>
  <version>1.3.50</version>
</dependency>

Why everything work for me and not on the other PC? Can someone please help? Thank you :)

Solution

The problem was that my friend's computer had a 32 bit system and the music library probably only runs on 64 bit systems.
