Error: catastrophic failure (exception from HRESULT:0x8000FFFF(E_UNEXPECTED))

when I am using Visual Studio 2017 on xps 17 laptop, I am using Class Wizard to add member variable into a MFC SDI demo, I got this error message:

catastrophic failure (exception from HRESULT:0x8000FFFF(E_UNEXPECTED))

I searched internet and I find these links. it gave me some thoughts to fix this error message.

1. Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))
2. Cycle Clipboard Ring Exception

the solution is one of them: start Visual Stuio as adminstrator. I will try this way and validate it.

"I am facing exactly the same issue. I have VS 2017 15.5.0 on windows 10."

I had this error come up fixed it buy running visual studio 2017 as administrator

the way I started class wizard is from class view in solution folder. then select the form view class->class wizard->cick tab: add memeber variable. this way will cause this error message to throw out.

my workaroun is to start from resource view->IDD_MYMFC15_FORM class( a class you are interested:). a form is opened. select the edit control I am interested-> right click->select add variable. a new variable will be added into this selected class, as this edit control in this example.
