First I want to apologize for my bad English, this is not my native language.

I bought the Tickstory soft at the 28/03/2016 ...version 1.7.4.0
At the beginning no problem and since a few weeks, when I try to lauch the MT4, a window open whith this message : A suitable laucher could not be found for your Metatrader version.
I read a lot of topics here and try all possible..... I checked the MT4 installation.....the path is ok...I install .net 3.5.....enter one more time the licence number....I get crazy !!!!
Could you help me please ?

Thanks.
Regards.
