Unity 5.1.2 does not run in Win10 for the first time (I haven't used unity before)

Hi everyone!.

I upgraded my OS few weeks ago from win7, and yesterday i decided to download Unity because a friend recommended it to me.

I’m using a 64 bits system, so i downloaded that version. As i said in the title, i have never downloaded unity before, so i don’t have a conflict with existing licenses.

The problem is that the Unity editor just don’t open. I can’t reach the welcome screen. I can only see a gray screen with nothing in it.

I tried the suggestions that i found in the troubleshooting page (Troubleshooting common problems with Unity 5.x Editor - Unity Answers) but i wasn’t able to solve my problem. I also tried other suggestion that i read in this forum without success (I tried to execute the editor in compatibily mode with windows 8, 7, etc).

Someone have an idea of what is happening?

I fixed it. I reinstalled it in the default directory.
