I Cannot Use Another Application at the Same Time as Modeler
If you experience problems using an application at the same time as Modeler, this problem may be caused by a TCP/IP port number conflict. You can view the port numbers allocated to other applications through the SERVICES file on your computer. By default, a Modeler installation will use the following port numbers:
1434 - for the Microsoft SQL Server service, sqlservr.exe
1433 - for the Microsoft SQL Server service, sqlbrowser.exe
27000 - for the PTC Integrity Modeler License Server service, which is used by the Floating License Server. The lmgrd port by default is 27000 but can be explicitly specified on the SERVER line.
SERVER myserver.mycompany.com ID 27001
It is necessary to define not only the TCP port that lmgrd will use, but also the port each vendor daemon will use. The vendor daemon port is random but can be explicitly specified on the DAEMON line. The 'PORT=' entry on the DAEMON line allows explicit selection of both externally available ports. 27001 is the TCP port reserved for use by the lmgrd process while 27002 is the port used by the vendor daemon process idl_lmgrd. Both port numbers must be unused by other processes. For example: DAEMON ARTSANSW PORT=27002
