0010241: On startup, it says "Index" file must be in "data" folder, i've checked and it is.
The Error box says,
"Main index file missing/corrupted. The file "index" must be in the "data" folder. Make sure DF decompressed into its folders properly."
I am unsure how to make sure a file decompressed properly but i have never had issues similar to this with any files, including DF, before.
For me, this error comes up every time i try to start DF. I am unsure how to reproduce this for others (as i only have 1 computer available to me).
If you need anything else, let me know.
No tags attached.

Where did you download df from? Is it the vanilla program from bay12games or a pack of some kind with utils and stuff included?

Have you extracted the zip file completely? Is the index file writeable?

This is typically an issue with permissions, e.g. 0011721. Make sure you have installed DF in a folder that you can write to, and that you have permissions to read and write everything in the DF folder.
