Something else to try, although a little more involved. Download the 'netfx_setupverifier_new.zip' file that appears right before the Comments section. Extract and run the 'netfx_setupverifier.exe' that is inside. Validate against '.NET Framework 4 Client':

If you're having problems with .NET, try removing it using this tool, scroll down a bit for the zip file:
http://blogs.msdn.com/b/astebner/archive/2008/08/28/8904493.aspxRun the tool and select ".NET Framework 4" from the "Product to cleanup:" list.
After .NET 4 is cleaned up, try reinstalling it according to step 9.

Reinstall .NET 4 Full setup with dotNetFx40_Full_x86_x64.exe
Download the file here:
http://www.microsoft.com/download/en/details.aspx?id=17718Or find this same file in the Universe Sandbox folder in Steam. Which is probably here:
C:\Program Files (x86)\Steam\steamapps\common\universe sandbox\Prerequisites\dotNetFx40_Full_x86_x64.exe
12
Double check that DirectX is installed correctly. Download and install this:

More obscure things to try:
3.5
Delete (or rename) the two settings files that are found here:
C:\Users\-your user name-\AppData\Local\Universe Sandbox
(the cause of this crash was fixed in 2.1.3, but it's still worth deleting these files as a last resort)
10
The iZ3D stereoscopic 3D driver may be incompatible with Universe Sandbox, if you use this, add Universe Sandbox to the exceptions list in its control panel.
11
Disable any video software like D3Doverrider software that forces triple buffering. This has been reported to cause crashes.
