Can't install Ndless on CX CAS Nspire with OS 4.0.0.235

[lazer155]

I followed the tutorial for Ndless 4.0. When I try to install the 4.0.3.29 OS, I get an error saying 4.0.3.29 is older than the current OS I have which is 4.0.0.235 and I am therefore not allowed to install it. I am using the 3.6 version of the nspire computer link software. This is the OS file that I keep trying to install which I believe should work with Ndless 4.0. It says 4.0.3.29. https://education.ti.com/en/us/software ... recxcas_os

What could I be doing wrong?

Never mind, I got it working. Ti connect kept trying to install an older OS version and I didn't notice that's what it was doing.

You must not use TI Connect for Nspire but you must use TI Computer Link
