Mathcad Prime 2 License Server Installation Problem

Hello, everybody.

I have met some problem when i want to install the Flex License Manager. So, here's the detail of the problem.

The server I want to install the FlexLM to.
The server is a virtual machine which hosted on a VMWare. The server couldn't connect to the Internet and already have another FlexLM instance which runs at least 5 other licenses. The server only have a network interface (which is the same as the PTC_HOSTID line in the license).
The documentation I've read.
What I've (which I think relevant to the problem) read was :
a. Mathcad License Problem - ptc_d daemon is down ... (Couldn't do it. The server doesn't have any PTC product installed yet.)
b. vendor daemon is not being read...File not found, __PTCD_PATH__ (Already modified the license like that)
c. Mathcad Prime 2 Installation, License Management section. (Couldn't use the setup file as the server couldn't and shouldn't connected to the internet).
The installer I have.
Mathcad 14 (don't know if the FlexLM can be installed and read the license for Mathcad Prime 2)
Mathcad Prime 1, Mathcad Prime 2 (the installer doesn't have the license manager)
The error I got.
