Answer:
After downloading MSSTDFMT.DLL, save it in C:\Windows\sysWOW64 folder.  Stay in sysWoW64 foder and locate the file cmd.exe.  Right click cmd.exe and click on "Run as administrator."  The black command screen appeares with
C:\Windows\system32>
Type in Regsvr32 C:\Windows\SysWOW64\MSSTDFMT.DLL
Now on the command screen entry you have:
C:\Windows\system32>Regsvr32 C:\Windows\SysWOW64\MSSTDFMT.DLL
Press "Enter"
This process finally worked for me after trying everything I found in help files that did not work.
