I have installed(repaire) vcredist_x64 and vcredist_x86,restart my computer,but it still have a issue crashing of MSVCR120.dll file. By the way, I have a error of vcredist_arm. It's not a effective win32 application.
How can I do to make the game startup?

Are you using a 32bit OS? The game requires a 64 bit OS.

My OS is 64 bit.

BTW, visual studio 2012 is installed in my computer. Is it essential to uninstall vs2012 and install vs2013?

No, certian programs will still use library files from 2012 as well as 2013 etc. If a VS file ever becomes redundant or obsolite your OS will normally take care of the situation for you.

Then how to make the game startup normal in my computer?

Bimooncat - could you post any screenshots of the error you mentioned? the vcredist_arm? Or paste it here?

2.I follow the address as you provide to repair MSVCR120.dll file.
I download three files:vcredist_arm, vcredist_x64 and vcredist_x86.
I choose "repaire" in the process of vcredist_x64 and vcredist_x86. Then restart my computer.
But vcredist_arm hadn't install success. The error is:vcredist_arm.exe is not a effective win32 application.
My computer is 64OS.
CPU:Intel(R)Xeon(R)E3-1230 v3@3.30GHz 3.30GHz
Graphics card:NVDIA Geforce GTX 970

3.Finally the game startup issue is never changed. I don't know what can I do to play the game.
I hope you can treat this problem. Thx.

The _arm error can be ignored, as that is only for ARM processors (like mobile and tablets).

If repair isn't working for you, I would suggest unistalling VC and then reinstalling both x64 and x86 (do not try to install VCredist_arm) It could be the .dll in question is bad and not being overwritten correctly when trying to repair.

Repair tends to be ineffective in my experience, if your having issues, its generally best to unistall and reinstall when possible.

I have unistalled VC and then reinstalled both x64 and x86. But the error is still exist.

Could you try removing your save & config folders? By "removing" I mean you can just rename the folder something like "Saved_Old" so you don't lose anything. I'm wondering if a config or save file may be corrupt in some way.

They are located here:

C:\Users\[username]\AppData\Local\RiverGame\Saved\

I open AppData folder, but have no RiverGame folder in it...(Because I never startup this game?No create?)
I found CrashDumps folder in it. The folders inculde as follow:
dwm.exe.1824
dwm.exe.1892
dwm.exe.3500
dwm.exe.5416
RiverGame-Win64-Shipping.exe.236
RiverGame-Win64-Shipping.exe.3352
RiverGame-Win64-Shipping.exe.4548
RiverGame-Win64-Shipping.exe.5328
RiverGame-Win64-Shipping.exe.5824
RiverGame-Win64-Shipping.exe.6404

Shot in the dark here, but perhaps windows isn't being able to call the file because of a permission issue. Have you tried running the game as administrator? C:\Program Files (x86)\Steam\steamapps\common\FlameInTheFlood, right click on RiverGame.exe and click run as admin. Just make sure steam is running when you do this.

If that doesn't work try running the RiverGame-Win64-Shipping.exe directly with admin privliges. The file can be found here C:\Program Files (x86)\Steam\steamapps\common\FlameInTheFlood\RiverGame\Binaries\Win64

I tried these two methods, but have no effect...

Damn....

Does the game act like its going to launch?(go black for a few seconds like its trying to load the splash screens) or does it throw the APPCRASH error right away?

I'm trying to think if your XENON cpu is not being liked by the game here, Intel XENON is typically a workstation CPU, and as such may not have all the capabilites a Pentium would have (Q series, i3, i5, i7) I'll look into that more though since I see that you play games like Don't Starve on your account so I might be howling at the wind here.

UPDATE: yup, never mind what I was thinking about the XENON....lol
