If you're having problems starting Universe Sandbox...
1 (If you're running the Steam version)
Try restarting Steam.
Try restarting your computer.
Download and install (or repair) these redistributables:
Microsoft Visual C++ 2008 SP1 Redistributablehttp://www.microsoft.com/download/en/details.aspx?id=5582
Microsoft Visual C++ 2010 SP1 Redistributablehttp://www.microsoft.com/download/en/details.aspx?id=8328
Install or reinstall .NET 2:
Download .NET 2 here:http://www.microsoft.com/en-us/download/details.aspx?id=1639
Or 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\NetFx20SP2_x86.exe
Double check that DirectX is installed correctly. Download and install this:http://www.microsoft.com/download/en/details.aspx?id=35
6 (Steam version only)
Make sure your video drivers are up to date:
In Steam from the Main Menu, select Steam > Check for Video Driver Updates...
6 (Standalone version - non-Steam)
Make sure your video drivers are up to date:http://www.nvidia.com/Download/index.aspxhttp://support.amd.com/us/gpudownload/http://downloadcenter.intel.com/
Other Things to Try
2 (Steam only)
Make sure Steam is up to date.
In Steam from the Main Menu, select Steam > Check for Steam Client Updates...
3 (Steam only)
Verify the installation (or re-download it).
In Steam, right click on Universe Sandbox in your Library > Select Properties > Click the "Local Files" tab > Click "Verify Integrity of Game Cache..."
Make sure that your copy of Windows is up to date:http://update.microsoft.com/
Go into optional updates and make sure .NET 2 is installed (select all of them to be safe).
Try creating a new Windows user.
In Windows, click Start > Control Panel > User Accounts... and create a new user.
Then log out and log in into the new user account. Try running Universe Sandbox from there.
(this will help determine if it's a user setting problem)
More Complicated Things to Try
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':http://blogs.msdn.com/b/astebner/archive/2008/10/13/8999004.aspx
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.aspx
Run the tool and select ".NET Framework 2" from the "Product to cleanup:" list.
After .NET 2 is cleaned up, try reinstalling it according to step 9 (above).
Getting the LNOMB error?
Download the file 't2embed.dll' and place it in your installation folder:http://universesandbox.com/forum/index.php/topic,5423.msg51840.html#msg51840
(this file will be added automatically in the next release)
More Obscure Things to Try
Make sure there aren't any unusual character in the install path:
Someone reported that A:\#Ste4m\SteamApps did not work, but that A:\1Steam\SteamApps did.
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)
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.
Disable any video software like D3Doverrider software that forces triple buffering. This has been reported to cause crashes.
If you're running Windows 8...
- Open up Local Security Policy
- Click on Local Policies > Security Options
- In the right box scroll down until you see "System cryptography: Use FIPS compliant algorithms for encryption, hashing and signing
- Double click and select "Disabled" > Click OKhttp://steamcommunity.com/app/72200/discussions/0/846940248059936510/#c846940248326546082
Why are the numbers out of order?
- The list of ideas has been reordered from most useful to try to least. The original number have been preserved for identifying different tasks..NET 2 or .NET 4?
US1 v2.0-2.1 required .NET 4.
US1 v2.2 requires .NET 2 which is less error prone to install.
