I am trying to install ndless on my TI nspire CX CAS and when I put the items into the folder, it says, "The operating system for this file is corrupt..." Would someone help me? I'd really appreciate it.

Sorry, this may be in the wrong topic, but I can't speak french. :/

It's alright to post in English on TI-Planet, and you're in the right section, "Problèmes divers" meaning "Miscellaneous problems".

You are probably using some version of TI-Nspire Computer (Link) Software which contains that misguided attempt at preventing users from doing things which are fully within their users' rights...
The third-party, free (llibre) software TILP program does of course not contain such user nastiness. For more than two years, on Windows, it has been (usually) possible to install TILP and TI-Connect / TI-Nspire Computer Software / TI-Nspire Computer Link Software side by side, after following a manual procedure which aims at working around a limitation of Windows, namely its hate for multiple possible drivers taking care of a single hardware ID. MacOS X, Linux or in fact, pretty much any other OS, do not have such a silly limitation.

I'm unsure about whether TILP (libticables) works on Windows 8, but that piece of crap remains, fortunately, infrequent enough.

Which system are you trying to install on your TI-Nspire CX CAS?

I'm told that error can occur in other circumstances, so I stand corrected

Indeed, before installing TILP, check that a) your calculator is running OS 3.1.0.392 and b) you're transferring the file which corresponds to your calculator model, i.e. the .tcc file.

Which system is currently installed on your TI-Nspire CX CAS?
