FlexNet Publisher
Encyclopedia
FlexNet Publisher is a common software license manager
from Flexera Software
which implements license management
and is intended to be used in corporate environments to provide floating license
s to multiple end users of computer software.
Computer software can be licensed in a variety of ways. A license to use a piece of software may be associated with a specific machine (node-locked), permitting it to only run on that machine (node in a network
); alternatively, a company may buy a pool of floating licenses and these licenses may be allocated dynamically to machines, a license being checked-out when a user begins using the software on any given machine and checked-in when the user finishes using the software. In this way, for example, a company might buy a pool of 50 licenses but support a user community of hundreds of occasional users of the software (so long as no more than 50 users ever want to use the software simultaneously).
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 the 1st of 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.
In October 2009 Acresso Software announced its name change to Flexera Software and FLEXnet Publisher was changed to FlexNet Publisher.
In July 2011 it's announced that Teachers' Private Capital, the private investment department of the Ontario Teachers' Pension Plan, has agreed to acquire a majority stake in Flexera Software from Thoma Bravo, LLC, a private equity firm.
The product is currently marketed by Flexera Software as FlexNet Publisher.
