FlexNet Publisher
Software license manager

FlexNet Publisher, formerly known as FLEXlm, is a license manager developed by Flexera Software that provides floating licenses for corporate environments. Unlike node-locked licenses tied to a specific machine in a network, floating licenses are allocated dynamically from a shared pool and can be checked out when a user begins using the software and checked in upon completion. This system allows organizations to efficiently manage software licenses by supporting many occasional users with a limited number of licenses, ensuring that no more than the purchased number of users run the software simultaneously. FlexNet Publisher thus facilitates versatile license management for software distribution and usage.

History

FLEXlm was originally a joint development by GLOBEtrotter Software and Highland Software in 1988. Highland's rights to the FLEXlm product were acquired by GLOBEtrotter in 1994; Highland continued as a reseller of 3rd party software. GLOBEtrotter was then acquired by Macrovision in 2000. Combining features from the Safecast protection system and FLEXlm, FlexNet featured product activation and executable wrapping, supporting floating licensing and node locked licensing models. Macrovision subsequently renamed FLEXlm to FLEXnet Publisher.

The original FLEXlm development team moved on to develop the Reprise License Manager (RLM) at Reprise Software in 2006.

On 1 April 2008 Macrovision's Software Business Unit, which included FLEXnet Publisher, was sold to the private equity company Thoma Cressey Bravo and subsequently relaunched as Acresso Software. It was a cash transaction valued at approximately $200 million.1

In October 2009 Acresso Software announced its name change to Flexera Software and FLEXnet Publisher was changed to FlexNet Publisher.2

A July 2011 announcement said that Teachers' Private Capital, the private investment department of the Ontario Teachers' Pension Plan, had agreed to acquire a majority stake in Flexera Software from Thoma Bravo, LLC, a private equity firm.3

The product is currently marketed by Flexera Software as FlexNet Publisher.4

Issues with bootloaders

Due to the way the digital rights management (DRM) works in FlexNet Publisher, FlexNet affects bootloaders; this makes FlexNet Publisher incompatible with drives encrypted with TrueCrypt56 and renders Linux-based systems unable to boot.78 The TrueCrypt developers also state that "the issue is caused by inappropriate design of the third-party activation software."9
