Can't open Arkham Asylum game from Steam

I requested a refund on Steam since nothing I tried was able to get the game to launch. I ended up buying the game on the Epic Games, and it launched and runs perfectly fine with no issues at all.

I can't think of much else to try.

• I have a couple of games from both Steam and EPIC that only launch if I launch them from my Steam\EPIC Library.
• If you haven't already, is there no benefit disabling Steam Cloud in the games Properties\General tab ?
• I don't think it would be an issue with a game of this vintage, but some newer games require you to have the current

gpu drivers and Win10 version.

• The only issue I have notes for regarding Bats-AA is it used to lock up when using the gpu, vs cpu with the high PhysX setting

(this was the original disc version).

Ah ha! I also just discovered this in my game problems notes...

I see that on another occasion I had a launch failure with Bats-AA that ended up being due to PhysX not showing up in Programs and Features

(the files were still in the Nvidia folders though). It seems this may have prevented the game from detecting PhysX, which with some

games needs to be installed, even when using AMD gpu.

.

It does not seem to be as common as it was a couple of years ago, but often the real source of the DX error was a corrupt .NET Framework

You may find repairing .NET will sort out the DX reinstall error (games say 'installing DX', but they are actually reinstalling\overwriting the DX files)

https://docs.microsoft.com/en-us/dotnet/framework/install/repair

However, this should only occur if trying to reinstall DX using the 'redist' installer in the games sub-folder, or using the

Download Details - Microsoft Download Center - DirectX Redist (June 2010) -

installer package (the same files as those in the Steam sub-folder but not yet unpacked), ends with an error.

• Or, if the Launcher.ini file is corrupted (reinstalling the game should have fixed this as well though), try deleting, or renaming

the Launcher.ini you find in your - StreamApps\common\BatmanArkhamAssylum*BmGame\Config* - sub-folder.

Then run Steams verify integrity of game files tool. This should replace the now missing file with a new one.

• btw... My Batman AA is currently on EPIC and the 'ShippingPC -Batman Game.exe' and 'BM Launcher.exe' are working, but I am having problems

with the 'advanced BMLauncher.exe' failing to load. This may only be a problem on Win11. I haven't verified if it is still working on Win10 yet.

Go figure eh! . Anyway... Good to hear you got the game going. By hook or by crook.

Thank you for your help. I tried all of these just now but unfortunately the game will still not launch. When I try, it loads for a few seconds and a Steam window opens that says "synchronizing Steam cloud" but then this closes after about a second.
