Unity 3 exe does nothing when run on windows 7 64 bit

Hi

Eagerly got my Pre release copy of Unity 3 but when I double click the exe after installing it thinks about it for 4 or 5 seconds then nothing happens.

I have tried all the compatibility modes to no avail.

Windows 7 64 bit (administrator)
Unity 3.0.0b

Any ideas?

 

Some more info found in the application log....

Oops, never mind. Had this problem before and posted a solution to it myself....

Here is fix..

Add unity.exe to windows DEP

Right click My Computer
Click properties
Click Link for Advanced System Settings on left
Select Advanced Tab
Click Settings button on the Performance section
Select the Data Execution Prevention TAB
Add Unity.exe to the list of exceptions.

 

or set it to only protect important system services as all do (all preinstalled systems are setup like that only the own installation breaks the DEP setup that way round normally)

 

Good to know thanks.

 

Thanks for the fix, now my Unity 3.2 works
