T-Splines 3.5 (Autodesk) for Matrix/Rhino x86/x64

Run Setup.exe and install eaither x64 or x86 (would not reccomend to install both.) after install, run rhino and go to the t-splines option and all the way to the left of the window, click t-splnes and click activate licence. (turn off wifi)and for serial number, enter random numbers, and it will say correct (a check mark) and for the serial key put "A46F1". After that run the keygen (eaither x64 or x86 depends on ur version that u installed) and after you enter the key, you will want to press patch on the keygen and after you close the activation, reopen it and u should be able to re enter the info and generate the key with the keygen and it should be good to go.
Note: a video on how to do it should be up soon, check the comments below for it
