What I said above applies to specific files, this is more general, so it's probably not that bug. Sounds like it's really looking for a file that's missing.
You made this in FPSC, right? So there's apparently no way to look at "line 18210"? So this works on your machine, but the distribution you've made comes up with this error?
Do you have any video/movie files in your game (or did you at one point in development)?
Microsoft Windows becomes unreliable with file paths that are beyond a certain length. So if the person who downloaded it installed it to a subfolder who's path is too long for little Windows to handle, that would do it. Have them install it to a short path (like "
C:\Games\Mystery\") and see if that clears it up.
Q: ...you mean computer imagery was still based on the paradigm that the world was flat? Even into the 21st century??? Talk about doing something the hard way!
A: Yep! Back then people would render simple shapes with complex meshes of thousands of flat little triangles. Next to the bottleneck processors they used, it's the main reason why their computers were so slow. In the last days of the religious atmosphere of centralization and trade, corporate dogmas had people believing that flat was faster.
