The 7.4.0 release brings with it a number of installation changes that long time Fledermaus users may want to be aware of.  First to be more consistent with other QPS products and company branding the software is stored under a QPS directory. On Windows this will be “C:\Program Files (x86)\QPS\Fledermaus” for the 32 bit version and “C:\Program Files\QPS\Fledermaus” for the 64 bit version.  On Windows the location of the preference files have moved as well. They are are now found in C:\Users\%username%\AppData\Local\QPS\Fledermaus, or "%localappdata%". Previously preferences were located in C:\Users\%username%\AppData\Roaming\IVS.

On Windows when you run Fledermaus to install a license file if you run it with administrator privilege the license will be installed in the licenses directory where the software is installed. However, if you install the license file as a normal user the license will be installed in the C:\Users\%username%\AppData\Local\QPS\Fledermaus\licenses directory. If you are installing a license for multiple different users on a windows machine make sure you install the license with administrator privilege or copy the license directly into the licenses directory where the software is installed.

Previous versions used an environment variable called IVSHOME7 to tell the system where the software was installed. As of version 7.4.0 this environment variable is no longer used and all configuration files are located based on a relative path from where the executable(s) are located. This makes it possible to better support the installation multiple versions of Fledermaus (or both a 32 and 64bit version) without any potential conflicts.

Please see our Installing Fledermaus on Windows guide, and Fledermaus 7.4.0 License File Locations knowledge base article for further information.

Everyone at QPS is pleased to announce that Fledermaus 7.4.0 is now available for download. Many new features and improvements have been made with this release:

  • The core rendering engine has been greatly improved and will take better advantage of modern graphic card capabilities. The greatest improvement with this release is for surface objects, which will now be much less degraded during interactive mode. The software now has a requirement that your graphics card support OpenGL 2.1 or newer.
  • QINSy projects can now be directly opened in Fledermaus and used with the Fledermaus area based editing tools. All edits are immediately applied to the QPS files in Fledermaus, so no unload is required.
  • The Mac OS/X distribution is now 64-bit and replaces the previous 32-bit version.
  • All Fledermaus applications now share a common installation location with QINSy. Common files, such as datum grid shift files are shared across applications.
  • You can now easily install separate 32-bit and 64-bit installations of Fledermaus (Windows only).
  • The Windows installation can now be installed locally for one user, or globally for all users of a machine.
  • The licensing management and user interface has been greatly improved and has better functionality for multi-user installations.
  • The Fledermaus applications now use a common geo-referencing engine with QINSy, which means all coordinate systems defined in QINSy are also supported in the Fledermaus tools.

Please check the Fledermaus Release Notes 7.3.4.a - 7.4.5.b for further technical details.

New Features in QINSy release 8.10.2014.01.28.1

In the latest release of QINSy (8.10.2014.01.28.1) the majority of the Line Data Manager functionality has been integrated into the Processing Manager. The Line Data Manager functionality may be found in a separate ribbon which becomes available after selecting a Line file in the Project Explorer pane. A Line file may either be newly created by selecting the New Line from the File menu or by importing from a AutoCAD DXF, DWG or Microstation DGN file. An option is also included to export the data to AutoCAD DXF file format where by the following AutoCAD versions are supported: R13, R14, 2000, 2004, 2007, & 2010.



Also in this release, Advanced Catenary Support has been added, where it is possible in real time to use advanced catenary tools to compute the tow cables & anchor chains involved in a rig move using a rig and one or more anchor handling tugs. This release of QINSy allows for a template file to be loaded and after which certain parameters may be changed in real time (i.e. tow wire length, anchor chain length, anchor status, rig and tug locations). During each computation cycle the catenary of both the tow wire and the anchor chain and the location of the anchor are computed after which they are displayed in the 3D Grid display.
