Open the command prompt (cmd) as an administrator on the server.
Navigate to the folder where you have the Password Manager installation packages stored.
eg: "c:\PM57\Password Manager\Setup>"
From the setup folder choose which installation package you want to run.
For the purposes of this article we will use "PasswordManager_x64.msi"
Run the following command
"PasswordManager_x64.msi" /l*v c:\Windows\Temp\install.log
Step through the installation process until you come to the error.
Take a screenshot of the screen with the error but make sure you include the time and date stamp on the bottom of the screen.
Send in both the log file and the screenshot to support for analysis.
