FEFLOW INSTALLATION PROBLEM

At the end of FEFLOW 7.0 installation, a window appears with the following text "The installation could not recognize one of these supported Visual C++ versions:
Visual C++ 2005
Visual C++ 2008
Visual C++ 2008 Express
Visual C++ 2010
Visual C++ 2010 Express
Visual C++ 2012
Visual C++ 2012 Express
Visual C++ 2013
Visual C++ 2013 Express
Visual C++ 2015
Visual C++ 2015 Express
The registration of the FEFLOW IFM wizard for Visual C++ can be performed later on by reinstalling the IFM SDK."

Visual C++ 2015 is already installed on my computer, so i don't know how to solve this problem.
Does anyone knows how to solve it? Thanks a lot

You need to install the IFM SDK. Usually, you can install the IFM SDK while installing FEFLOW. If FEFLOW is already installed you can install the IFM SDK afterwards. If you use Windows OS, please go the Control Panel and then to Programs and Features. Right-click on your FEFLOW installation and choose change and modify the IFM SDK by activating.
