CoCreateInstance () Failed

Posted by MaxStation, 27 January 2012 12:00 am

 When opening max files you get CoCreateInstance () Failed error message.


From Start Menu do a search for CMD  

Do a Right click on cmd.exe and run as Administrator


Go to your 3ds max install folder: cd "C:Program FilesAutodesk3ds Max 2012"

First Unregister :  regsvr32 /u MAXComponents.dll

While unregistering you may get an error message that the dll could not be unregistered, you can safely ignore this message.

Secondly Re-register: regsvr32 MAXComponents.dll

If registered sucessfully you will see this screen

Simply running Max as Administrator (right-click on max and select run as Admin) then applying skin to an object will fix this bug.

For those who get error messages when trying (not the one that was mentioned above), try using 'regsvr32.exe' instead of just 'regsvr32'

I'm using Max 2014, and it doesn't have the CMD file or 'regsvr32.exe'
Is there another way?
*NOTE: The error message shows when I use the Skin Modifier

Thank you so much! I was so afraid I lost all skinning data
