FileUltimate v5.9.0 is released

This release includes the following changes:

  • Changed: Licensing model. From now on, the license types are Professional, Enterprise, Distribution and Source. Your existing license type (Developer, Developer OEM, Site, Site OEM) will still be valid but license keys are changed so please go to and acquire a new license key if you want to use this version (or higher). If your one year maintenance has not ended, you will receive a new license key without a charge. After your maintenance has ended, you will be able to upgrade to only new license types.

  • Fixed: DocumentViewer was not displayed in IE11 with “Please use an HTML5 Compatible browser” error when IE Enterprise Mode was active. This is because Enterprise Mode emulates IE8 and DocumentViewer supports IE9+. Now DocumentViewer will force latest IE mode and will display as expected even in Enterprise Mode.

  • Improved: Real version will be shown in “Description” field of Visual Studio reference property window. This is the FileVersion of the DLL, Visual Studio by design shows AssemblyVersion in “Version” field of that window which confused some developers. AssemblyVersion is changed only when there is a breaking API change which requires a recompile so it’s not changed often, however FileVersion is changed for every release. This way, the developer can make sure exactly which DLL version is referenced from within Visual Studio (no need to go to Windows Explorer
    and check file properties).

  • Fixed: Setting FileUltimateConfiguration.Current.TrialExtensionKey did not have effect immediately, it was delayed for about 20 minutes.
