Issue:

A Revit model keeps crashing with messages such as: "too many missing elements," "an unrecoverable error has occurred," and so on.

In the Revit journal, you see the following line:

ApplicationException is being thrown on behalf of the function <bool __cdecl FilterCategoryRule::setCategories(const class crs::Set<class ElementId,struct std::less<class ElementId>,class tnallc<class ElementId>

Causes:

There is a problem with the Revit.ini file in C:\Users\<username>\AppData\Roaming\Autodesk\Revit\Autodesk Revit <version>.

Solution:

Locate the Revit.ini file here: C:\Users\username\AppData\Roaming\Autodesk\Revit\Autodesk Revit xxxx
Replace it with the Revit.ini file found here: C:\ProgramData\Autodesk\RVT xxxx\UserDataCache

To replace the file:

  1. Close all instances of Revit.

  2. In C:\Users\username\AppData\Roaming\Autodesk\Revit\Autodesk Revit 2017, locate Revit.ini. Save a copy of this file to your desktop. (You will overwrite the original copy of this file in step 4, so keep a copy until the process is complete.)

  3. In C:\ProgramData\Autodesk\RVT 2017\UserDataCache, locate Revit.ini, and copy it to the clipboard (Ctrl+C)

  4. Go back to C:\Users\username\AppData\Roaming\Autodesk\Revit\Autodesk Revit 2017 and use Ctrl+V to paste the copy of Revit.ini into this folder (overwriting the existing copy).

  5. Open Revit to test whether the problem is resolved.
