Hi,
in current Windows version I use the following method:
1.]
On license server I install FLEXnet 10.8 (available on Proe WF5 DVD)
2.]
I modify license.dat to contain two lines similar to the following ones
SERVER servername PTC_HOSTID=serverMACaddress 7788
DAEMON ptc_d D:\PTC\flexnet\x86e_win64\obj\ptc_d.exe D:\PTC\flexnet\licensing\ptc.opt port=7789
3.]
I restart license server.
4.]
I define Inbound rule in Windows Firewall to enable communication via 7788,7789 TCP ports.
