Extract CATConstraintModeler.dll from .zip. We recommend that you extract CATConstraintModeler.dll to the installation directory of the program that is requesting CATConstraintModeler.dll.
If that doesn't work, you will have to extract CATConstraintModeler.dll to your system directory. By default, this is:
C:WindowsSystem (Windows 95/98/Me)
C:WINNTSystem32 (Windows NT/2000)
C:WindowsSystem32 (Windows XP, Vista)
C:WindowsSystem32 (Windows 7/8/2008r2/10/11)
C:WindowsSysWOW64 (Windows 7/8/2008r2/10/11)
If you use a 64-bit version of Windows, you should also place CATConstraintModeler.dll in C:WindowsSysWOW64
Make sure overwrite any existing files (but make a backup copy of the original file).
Reboot your computer.
If the problem still occurs, try the following:
Open Windows Start menu and select "Run...".
Type CMD and press Enter (or if you use Windows ME, type COMMAND)).
Type regsvr32 CATConstraintModeler.dll and press Enter.
