Technical Note 91786

Targets:
All

Component:
Licensing

Note: - This applies to legacy versions of IAR Embedded Workbench (2013 and older) which used License Management System version 1 (LMS1).

Introduction

This Technical Note gives advice on using the IAR License Server (LMS1) to share licenses over a local network.

Discussion

The limitations are important, because the legacy technology in LMS1 (last release 15/June/2011) imposes limitations not expected today.

Read the limitations thoroughly, find a physical PC with one of the old supported Windows systems, then download and install the LMS1 License Server application.

These limitations apply:

  • The server computer must have a static TCP/IP address.
  • A license request might fail (or work intermittently) over VPN.
  • A license request might fail if performed from (or to) another local network.
  • The license server application might work on a virtual computer. However, note that the LMS1 license server application tries to detect and block itself on a virtual computer.
  • Microsoft no longer supports the Windows versions on which LMS1 was tested, so your IT department might not allow installation of the legacy LMS1 License Server application.

Supported operating systems:

  • Windows XP, 32-bit version
  • Windows 2003 server, 32-bit version
  • Windows Vista, 32-bit version
  • Windows Vista, 64-bit version
  • Windows 7, 32-bit version
  • Windows 7, 64-bit version
  • Windows 2008 server, 32-bit version
  • Windows 2008 server, 64-bit version

Because Microsoft no longer supports any of these operating systems, the advice is to use LMS1 server licenses on a local network, which is not possible to reach from the Internet.

Downloading and Installing:

Conclusion

The LMS1 server license system works on older Windows systems running on physical computers in a local network.

The LMS1 might work on modern Windows systems, when communicating between different networks, and in virtual computers, but all such usage is unsupported.
