I can´t open simulink

After I typed and enter "simulink" this came up: "Can't reload 'C:\Program Files\MATLAB\R2017a\bin\win64\sl_graphical_classes.dll'" It was working a week ago, I opened simulink with no problem, but now it's not working. I already tried reinstalling but I couldn't fix it. I'm using a Lenovo ideapad 319 with windows 10 Home (64 bits).

Which antivirus are you using?

[Miguel Ángel Macías Lazcano]

ESET smart security

Answer 1

[Santosh Prasad Choudhury]

You have licesense or trial version.

[Miguel Ángel Macías Lazcano]

License. I did use simulink this week. Maybe a windows update or an antivirus update did something wrong.

Answer 2

[Andreas Goser]

This looks like being related to this bug report

[Andreas Goser]

However, the directory of your installation looks like you use R2017a, the respective bug however being fixed in R2016a. Maybe it is a related issues that resurfaced.

[Walter Roberson]

That bug is what I thought of but it was specific to Dell and not Levano

[Miguel Ángel Macías Lazcano]

I read about the bug, but, as you say, I use a Lenovo. I also use Matlab in a HP laptop and it works fine there. Thank you for your replies, if I find the solution, I'll post it here.

I'm having the same problem(same error), my computer just run a windows update automatically, and I can't open my Matlab R2018a, but the R2016b runs fine though, I have no idea what's going on.

PS. I'm using a Win10 desktop, thought this bug only occurs in Dell, that's really weird.
