## Solution

Procedure
=========

To install the Harmony Endpoint client using MSI through a command line interface, run this command locally as administrator on the computer:

`msiexec.exe /i <path to msi>\EPS.msi `  

For example:   
`msiexec.exe /i C:\users\admin\EPS.msi`  

Troubleshooting
---------------

Run `msiexec.exe /i EPS.msi /l*v <logname>`. For example, `msiexec.exe /i EPS.msi /l*v EPSinstallation.txt` and share the log file with Check Point Support.
