Isn't opening [solved]

[th3artist]

I'm new here and I'm trying to open the Substance Painter for the first time ever.
When I click to initiate the app, everything is normal. It appears a screen saying "Substance Painter", "Summer 2018", "a painting" and everything, you guys should know what I'm talking about.
Then, 5 seconds later, that screen disappears and nothing more happens. The app should start but nothing happens.

Someone here can help me, please?
Thank you so much! Really appreciate that!

UPDATE:

The log says: [ ERR] <Qt> "[DBG ERROR][OpenGL Helpers]" "Non OpenGL 3.3 capable hardware"
My RAM memory isn't sufficient. That's the problem I think.

I can't say what the problem might be, but the first item would be to attach a log file as in this link.

Even though it didn't run, I think there should be a log file.
