Registax 3 will not ope AVi files

[Fay]

Hello, I have just bought a DMK 21AU04 mono camera.

I have settings as Y800 & tried CODEC Unspecified but cannot open in REGISTAX. Message "Failed to Start AVI Decompression"

Can it be beacause version 3 does not support uncompressed data?

Thanks

I think I am ok now. Downloaded Registax 4 & put Unspecified as CODEX
