wait for msiexec to finish

If you are trying to use msiexec the windows installer, my experience has taught me that it immediately returns command to the user as soon as it starts executing. This is a problem in a script that depends on the install being done. If you want control to be returned only if the install is complete then try Start-Process. I didnt get all the way through the documentation for it but i did get as far as solving my problem;

msiexec /i "SSOMMCSnapInSetup.msi" /qr /log somelog.txt
returns right away but

Start-Process -FilePath msiexec -ArgumentList /i, "SSOMMCSnapInSetup.msi", /qr, /log, somelog.txt -Wait
only returns after the install is finished.
