HERE'S THE FIX FROM MICROSOFT:
Type command prompt in your windows start menu, right click and run as administrator, and allow it to load
Then type these commands below (one line at a time) in the command prompt box that pops up, right after C:\Windows\system32>
TAKEOWN /F c:\windows\syswow64\riched20.dll /a
ICACLS c:\windows\syswow64\riched20.dll /grant administrators:F
ICACLS c:\windows\syswow64\riched20.dll
CERTUTIL -hashfile c:\windows\syswow64\riched20.dll sha256
Run these two commands in addition:
ICACLS c:\windows\syswow64\riched20.dll /grant "NT AUTHORITY\SYSTEM":(RX)
ICACLS c:\windows\syswow64\riched20.dll /grant "BUILTIN\Users":(RX)
...afterwards, type EXIT on the command line.
your're welcome!
