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 '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:
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 !!!
