I just downloaded and tried to install a student verison of 3DS Max 2015. When enter a serial number and product key shown on the download page, the serial number gets a green checkmark, but the product key has a red X next to it despite typing in the exact product key given. Any matter to help fix this issue would be greatly appreciated.
Hi @MATTt3D,
Welcome to the Community. This could be related to the incident with the 3ds Max 2015 download which is downloading Autodesk 3ds Max Design 2015 instead. We are looking into it right now.
In the meantime, try downloading Autodesk 3ds Max 2015 using this link instead: Autodesk 3ds Max 2015.
Alternatively, you can re-download the installer from our Virtual Agent instead (click on Download Links -> click on 3ds Max Products -> click on Autodesk 3ds Max -> click on the link under 2015 to start the download).
Let us know if this helps or if you'll need further assistance from us. Thanks,
