Error caused by Microsoft Forums

Hello there,
I have this error caused by Microsoft Forums and I don’t know how to fix this DLL issue. I searched on the Internet for download and didn’t find it. Also I installed a DLL fixer and I still have this error. Can anyone help me please to fix this? If I find this DLL file how I can install it?
Thank you!
