I am trying to install flash player silently, using a powershell script. I do not think it is being installed. I looked under "control panel->uninstall programs" I don't see flash player listed there.
Also, I am printing the exit code for the process and it prints 1603 exit code, which is "fatal error during installation"

As an experiment, I double click on the flash player .msi file, and it gave me 1722 error " Error 1722.There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. "
