MT4 does not work after re-installing Windows 10

[Alonso Santamaria]

Hello.

I have downloaded MT4 from both BDSwiss and Alpari. They were working perfectly fine, but I reset my laptop and fully reinstalled Windows 10. Now they do not work. They do not give any error message, simply, they do not start. When I click on the program's icon the clock shows for about ten seconds, then nothing, nothing at all. No warning, no error, nothing. 

I have tried to run it in Administrator mode, same thing. I tried to run the Terminal.exe program as compatible with past Windows versions, same thing. 

MT5 runs perfectly fine, but my accounts are not recognized since they are MT4 accounts.

Is there any log where I may find out what is happening? Has this issue already been detected and fixed?

Thanks.

Hello. 

Thanks for the help. In fact, I installed MT5 just to test and it works fine. But MT4 does not launch. Unfortunately, my accounts are not recognized in MT5.
