Error when installing Oss Pbx Endpoint Manger

Hello guys
im a newbie to Asteriks/freepbx and this is my first install
My server version is "FreePBX 13.0.192.16 'VoIP Server"
When trying to install the free endpoint manage of the “OSS PBX End Point Manager” i get an error like this

"Installing endpointman
Error(s) installing endpointman:
Failed to install OSS PBX End Point Manager due to the following conflicting module(s): EndPoint Manager"
Any help will be approciate

you are trying to install OSS EPM however, as the error states, Commercial EPM is already installed …

remove it then try installing OSS EPM

Thank Chris
However When I go to into The Modules Admin Gui
I see no OSS EPM
I also checked the cli command

fwconsole ma list | grep -I EPM
i get nothing about it ?

Uninstall endpoint manager not EPM.

when i try to “uninstall/remove/disabled” i get error
EndPoint Manager cannot be disabled because the following modules depend on it:
restapps
Please disable those modules first then try again.
“restapps” does not apperes to be in the module list ???

fwconsole ma uninstall restapps endpoint

Hi Thanks it is working !!!
