Unity 2.5 crashing on start up

[Bren]

Heya,

I’m trying to run a freshly downloaded/installed Unity 2.5, but it’s crashing on start up. No window, no nothing, just the “Unity Editor has stopped working” dialog.

Tried a reboot as well.

I’m running Windows Vista Ultimate x64, SP1.

I can’t find the editor log to send. Where is it located?

Problem details, FWIW:

If I remember correctly from the beta list, Vista needs some security setting to let Unity run.

Being a Mac person I cant help you further on. But check the documentation to see if it mentions anything about that

Im getting the same problem. Its really bugging me… Hopefully there is a patch or fix available.

Edit: I think I figured it out. Atleast this is whats in the Q A

Q) I’m using Windows Vista, and every time I launch Unity I see a message “Unity Editor has stopped working” before I can do anything. What’s the deal?
A) Due to a bug in Vista, some machines need to have “Data Execution Prevention” disabled before the Unity Editor will run. To disable it, go to Start->Settings->Control Panel (Classic View)->Performance Information and Tools->Adjust Visual Effects->Data Execution Prevention. Enable the option “Turn on DEP for all programs except:”, then click Add, and add the Unity Editor.

Here on my Computer it is working with Vista Home Premium 32 bit and SP1.

Sorry not helping you but just want to inform you.

This worked! Thanks fitzy.

I am having the same problem.
Unity fails to start in Vista.

It was working until I tried installing Blender Python. After removing Blender Python it still fails to start. I even re-installed Unity with no improvement.

It appears there is some remnant of Unity somewhere that I am not cleaning out during uninstall.

Are there some Unity registry settings that need to be cleaned?

Disabling DEP for the Unity Editor worked for me as well, however after a few weeks of on and off trying to figure out this problem i’m a bit put off. I still have not found the Q&A section referenced by the poster (thank you very much sir for posting the info!) and i found nothing in either the Unity manual or the Unity FAQ that mentions this. It was only by searching the forums that i happened across this post.
