Xaml Error and Reset Ribbon

By Adnan Hussain

Software: 3DS Max 2011

OS: Windows Vista

During startup of 3DS Max I have run across this error. First a window will appear:

Followed by:

You can click through these error messages and still launch the program, but our ribbons menus will be gone.

The problem is that a file called MaxManaged.xaml has become corrupt for whatever reason.

First close 3DS Max.

You can find the MaxManaged.xaml file in your user, appdata folder, which for me was:

C:\Users\<username>\AppData\Local\Autodesk\3dsmax\2011 – 32bit\enu\UI\

You’ll notice that this file has a size of 0KB if it is corrupt. Simply delete it, and make a copy of the backup file MaxManaged.xaml.backup, renamed to MaxManaged.xaml.

Relaunch 3DS Max and you should be good now. Unfortunately, this problem is likely to occur again, but at least now you have a solution.
