[Crash] Starting a new game on a fresh install results in the title crashing after loading screen

Game crashes after initial install when trying to start a new game. 

Crash log crash point: 

ERROR: Couldn't write Access to the path "C:\Users\xxxxxxxxxxxxxxxxxx\Documents\Klei\OxygenNotIncluded\WorldGenSimSave.dat" is denied.   at System.IO.FileStream..ctor (System.String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean anonymous, FileOptions options) [0x00337] in /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/FileStream.cs:354

Additional info:

No savegame files are written in the savegame file location (makes sense since the game crashes before the save is done). 

Attempted workarounds: 

1. vcredist_x64.exe reinstall (2015 version)

2. windows update check and install

3. unticking savegame folder "Read Only Access" 


The long and short of it is i'm gonna request a refund and probably skip on buying this game altogether. I understand it's early access and the inherent risks (both related to client and developer) this implies, but a walkthrough breaker 3 clicks into the game is unacceptable, even at public alpha stage.

Best of luck to you all, the game looks fantastic and fun. Hope all your future games release in a playable state! 

I'm delighted i managed to get it to work. The game seems really entertaining.
 

EDIT: 
Found fix for the issue.

Cause: Game unable to write savegame files to it's savegame directory.
Solution: Uncheck the "Read only" box on your "Klei" folder ( full path C:\Users\xxxxxxxxxxxxxxxxxx\Documents\Klei\") 

Dev suggestion: please address this issue in a future patch if possible, or at least include it in the FAQ section.
