same here. i get a message to run the application in safe mode, but it doesnt start up.
Universe Sandbox has encountered a problem.
Would you like to try running in safe mode next time?
Safe mode uses fewer graphical features which
may allow Universe Sandbox to run successfully.
no matter which option i chose, the loading ring icon loads, then this message pops up.
Die DLL "SteamworksWrapper.dll": Das angegebene Modul wurde nicht gefunden. (Ausnahme von HRESULT: 0x8007007E) kann nicht geladen werden.
Error Code: 2.1.0 Steam - PPOHO
rebooted PC like suggested, didnt fix it. verifying game cache in steam did not fix either. taskmanager shows a "form1" task which i have to force kill and to uninstall the software through steam, i have to restart steam again.
not sure if it helps, but my steam is not installed on my main C: drive. only OS/drivers and random software.
core i7 860
nvidia gtx 280
win7 pro 64bit on SSD
pls fix
