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).[original research?]

History

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.[2]

In October 2009 Acresso Software announced its name change to Flexera Software and FLEXnet Publisher was changed to FlexNet Publisher.[3]

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.[4]

In 2020, Flexera Software rebranded its supplier division as Revenera[5], which currently markets the product as FlexNet Publisher.[6]

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 TrueCrypt[7][8] and renders Linux-based systems unable to boot.[9][10] The TrueCrypt developers also state that "the issue is caused by inappropriate design of the third-party activation software."[11]
