The latest version of PIPENET is PIPENET 1.9.0. When updating an older version of PIPENET to PIPENET 1.9.0,  network licence users also have to update the version of FlexNet Publisher (formerly known as FLEXlm) on the licence server. PIPENET 1.9.0 requires FlexNet Publisher 11.14, whereas older versions only required FlexNet Publisher 11.6. The newer version of FlexNet Publisher can be found in the Licensing directory of the PIPENET 1.9.0 installation CD.

To install the new version of FlexNet Publisher, first stop the existing FlexNet Publisher service. Then replace lmgrd.exe, lmtools.exe and sunrise.exe with the versions found on the PIPENET 1.9.0 installation CD. Then in LMTOOLS, set the paths for lmgrd.exe, the licence file and the debug log file and start the new service. The existing PIPENET licence file will still be valid with the new versions of FlexNet Publisher and PIPENET. Older releases of PIPENET can also still be used with the new version of FlexNet Publisher.

We strongly recommend customers to use the latest version of PIPENET at all times to ensure you have all of the latest features. With more than 100 new features in PIPENET Vision 1.9.0 there is a lot of additional functionality to enjoy in all the three modules of PIPENET.
