You can use a log file to verify that an installation succeeded.
To create a log file describing the installation, append /L C:\path\setup.log to the install command and scroll to the end of the log file to verify.
The following is an example of creating a log file:
msiexec.exe /i installer.msi /qn /L C:\path\setup.log
This example causes the log to be written to the C:\path\setup.log file.
