[Windows] DST 64 bit doesn't open, no crash messages, windows, just nothing

did you try reinstalling the game

I had the same issue.

Immediate crash when you try to load the x64 bit version of the game.

The issue: Missing x64 bit Microsoft Visual C++ redistributible in: steamapps\common\Don't Starve Together\VCRedist

The only one there is the x86 one, and steam doesn't know what to do and crashes. 

This is not caught by the logs in the client_log, and that only shows:

[00:00:01]: Steam doesn't seem to be running. Trying to restart the game via Steam.
[00:00:01]: Error, Steam failed to initialize, result=1...
[00:00:01]: The application will now exit

 

Solution: Download the latest x64 Microsoft Visual C++ redistributable from Microsofts (here's a quick link to Microsofts official download page).
https://docs.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170

Long Term Solution: KLEI PROGRAMMERS please add this x64 bit redistributable to the file path so people that don't happen to already have it can run without this problem. (I only had it because I had to reimage my PC recently!!).

 

Thanks,
