Patch manager issue

Hi all, I hope you are well

I have 5 modules(NPM, SAM, NTA, VNQM, and NCM) installed on one server and uses an SQL database located on a different server. I tried installing patch manager inside the server which contains these 5 modules, when the install completed I noticed services disappearing from Orion services manager.*like after installing only few services were present*). . should I install patch manager on a separate server. I want to ask what's the best practice for this. please help

Thanks
