Its happened to me a number of times . I found that it was my screen resolution .

sometimes ,usually when my comp crashes, my BIT goes down to 8bit or 16bit ...this wouldnt let zero open ...as soon as i change it back to 32 it opens

So I finally experienced this problem that many of you have - Zeroeditor would not launch, not even when opening it directly.

Welcome to our world Just kidding.

You can also try to use specialized sofwares to correct that... Registry Mechanic or the Registry management tool included in Norton SystemWorks suite can fix errors faster than Windows Restoration function...

Less risky, I guess...
