So I continue to have this problem in 0.15.30 and Symantec Endpoint anti-virus. The errors occurs for both the stand alone .zip as well as the steam version of the game, the msi does work even though it still throws an error (detailed results below). I would tend to agree with you that this is not a long term solution - I fear 0.15 launching to steam and a large number of users having this problem. Is there a way to reassign this bug to open items?purdueme91 wrote:Edit 3: The standalone version from factorio website fixed the issue. So anyone else having the issue specifically with it not launching through Steam can follow the steps on the download screen to link your steam account to factorio and download a standalone version.
0.14.23 - (steam and standalone .zip & .msi launch)
0.15.30 - (steam and standalone .zip DO NOT launch)
0.15.30 - (standalone .msi installer antivirus alert pops up, however, install finishes and the game launches)
