Unity Crashes on startup

Hello, every time I try to launch unity 5.1 it shows the unity screen but it just instantly crashes and says that Unity Editor has stopped working. I tried to reinstall but it didnt change anything. Any help on finding a solution? I use a desktop with windows 7,i3 and nvidia geforce… _Tks

It is impossible to give you an answer with the data you provided. Could be int.MaxValue diferent things.

btw i just instal the unity 4.6.7 and it is all right

Had same problem, and I solved it… Instead of downloading 64bit unity installation get 32bit.

Hope it solved your issue too.
