Urgent HFSS 15 unable to locate or start COm engine

Dear All

I have just installed HFSS 15 with a licence over server. HFFS can run simulations on the local machine but not able to run simulations on any of the two servers I have
dose anyone have a clue about this?
I have LInux but have installed HFSS on the Windows on My virtual Machine and everything is through my university network
I would like to run my simulations on one of the powerful machines in our network
currently I can get the licence for the sever but I can not run simulations and get the error "unable to locate or start COm engine"

Thanks

do you have hfss installed on servers?

No HFSS is installed on my PC
I get the key from the server

You need hfss installed on any machine that you are going to solve on. Install copies on your servers.

Yes I have it installed on both computers sorry for my bad communication

For remote solve: general options->Analysis options-> click the remote solve radio button, enter IP, DNS or UNC, of server. You may also need to setup Remote analysis options since you have multiple IPs for your computer.
For distributed solve: you need one instance of your own machine in the computer list and it needs to be the first computer in the list.
