I've seen some people getting an error including some random numbers followed by "riched20.dll" in soldat 1.5. The error is caused by installing soldat on a computer with the wrong version of that dll.
To fix that error do this:
1. Download:
http://hem.bredband.net/jacob92/riched20.dll.
2. Place it in your soldat folder.
3. uhm... Done!
