Trouble with HKXCMD

[CanisLupusFan]

Hello! I am trying to convert some .hkx files to .kf, however as I enter the following command in cmd:
>hkxcmd exportkf "skeleton.hkx" "Input" "Output"

The conversion fails, as the Output folder remains empty, and I only get this message:
>------------------------------------------------------------------

> Animation   : PcXs (expires PERPETUAL)
>------------------------------------------------------------------
Could anyone please explain what this means and what am I doing wrong? Thanks.

First of all did you make sure your files are 32bit oldrim hkx and not 64bit as hkxcmd cannot convert 64bit hkx files. Secondly I would recommend this as it is a bit easier to use https://www.nexusmods.com/skyrim/mods/17109?tab=description. 

If you need to backport the hkx files here is a guide https://www.nexusmods.com/skyrim/mods/104459

I usually get this error due to 64 bit files or the file name is wrong

Thank you very much! I was indeed using SSE's 64-bit .hkx files. Using the 32-bit ones worked!
And thank you for the recommendations, these will surely come in handy.

Glad I could help. Oh and one last tip. Always use the 32bit hkx files and them convert them to SSE when they are done or to test. No tool that I know of is able to mess with 64bit hkx files.
