    Hello Mfc120u.dll,


    This is usually caused by a wrong or corrupted C++ Redistributables  installation.

    To correct the problem please proceed as follows:

    -Start vcredist_2013_x86.exe located under C:\Program Files (x86)\F-Secure\F-Secure Booster\  

    -Install it 

    -If you get the question "install or repair", please choose repair. 


    After this step it should work.
