2, then find the cmd.exe file under C:\\Windows\\System32, right click and select “run as administrator>;

3, at the command line Window input:

regsvr32 msi.dll

and press Enter, prompt "DllRegisterServer in msi.dll has been successful",

4, re-install Office software again. In the same way, installing other software encounters "Error 1719" problem, and it is also solved.
