my Unity editor 5.6.0 (32 bit) can't be opened

I use Unity version 5.6 32 bit when I open the program appears dialog to open or create new project. But after I open the project does not appear unity editor. But when I check in task manager there is unity editor. This case is the same as before when i use that 64 bit version. Anyone help me to solve this problem? Additional information: I am using Windows 7 64 bit SP 1 I have tried to reinstall Unity and restart my laptop but it's the same ![alt text][1] ![alt text][2] [1]: /storage/temp/92694-unity.jpg [2]: /storage/temp/92695-aaa.jpg
