In our case, we had to add local PC “Users” permissions for Full Control to this file:

I recommend that you review each PackageContents.xml in the ProgramData location to check for appropriate permissions.

Basic fix method found at:
Other possible solutions:
  • Delete Autodesk, Inc. folder
  • Delete cascade
  • Make a new user profile and see if that works
As per:

“As an alternative to controlling Revit tools and analysis features using the Options dialog > User Interface tab, you can define the DisciplineOption setting in the Revit.ini file.”

Heads-up from Steve at:
Revit OpEd: User Interface Configuration Calculator

If you have just installed a fresh version of Revit, you may have noticed that you have lost your Custom Colors.  There are 16 ‘slots’ available for Custom Colors in the Revit Color Palette.

To transfer the colors from one installation to another, just copy the [Colors] subsection from the Revit.ini file from the old installation location to the new one.  For example, if you previously had Revit installed on drive Y: in Vista, and you now have a new installation on drive C: with a new OS, do this:

  1. Close Revit.
  2. Open Revit.ini from “Y:Program FilesAutodeskRevit Architecture 2011ProgramRevit.ini
  3. Open Revit.ini from “C:Program FilesAutodeskRevit Architecture 2011ProgramRevit.ini”
  4. Copy the [Colors] section from the older / original Revit.ini to the new, fresh  Revit.ini
  5. Save and close the file.

Here is some other information about the [Colors] section –
The first three entries in the [Colors] section defines the user interface colors from the Options dialog, Graphics tab:

A default installation will look something like this under [Colors]:

If you really hate the ribbon (also widely known as DLM – Drunken Leprechaun Mode) in 2010, give this a go:

  1. Create this file:
    C:Program FilesAutodesk Revit Architecture 2010ProgramDebug.ini
  2. In this file, type:

When you next open Revit, you will be using the ‘Classic’ UI.If the above is too much of a pain for you, go to and get the AutoHotKey executable that does it for you (you will need to login).

If you want to use your 2009 Keyboard Shortcuts, make a copy of your 2009 keyboard shortcuts file in your 2010 program folder and rename it “KeyboardShortcutsOld.txt”. Restart Revit.

(it really does work)

Thanks to ArchTech and the AUGI Forums for this.Use this at your own risk, and keep in mind that Autodesk will not support issues specifically related to use of the ‘superseded’ user interface. Enjoy!
