Game won't launch (Windows 10)

[JCvgluvr]

Like others, I seem to be having trouble starting the game. I hit "Play Game," a box pops up preparing to launch. Then the box disappears, and nothing happens. Unlike other people, all solutions I see are for Windows 7 and 8. I'm running the latest update of Windows 10. I know this for a fact. So...what now?

Played the game on the Switch today, using a $20 gift card I had. It was so much fun! The game is absolutely wonderful! Made it past Flying Battery! The Chaos Emerald stages kind of suck, but otherwise I'm in nostalgia heaven!

The best part was not having to screw around in file explorer for ever and ever, just to overcome unsolved problems by the game's developers! This is why I'm glad that I play both consoles AND pc! I get the benefits of both. Ultimately, I suggest that's what people do, here. It might feel good to overcome obstacles in the way of your game. But sometimes...it's just not worth it. There's more than one way to skin a cat, people!

I'm glad to see you are having fun with Sonic Mania.

That's odd. I'm using Win10 and Avira and it works alright. You sure it was related to DLL files?

What platform you use to enjoy the game doesn't actually matter. What matters is that you at least enjoy it!

A summary for future users: Sometimes the automated installation of the prerequisites for Sonic Mania can fail for some unknown reason (probably badly scripted). The fix is actually rather simple:

64-bit users should install both x86 and x64 installations, while 32-bit only need to install x86!

1. Right click Sonic Mania in Steam and click on Properties.

2. Navigate to the Local Files tab and clikc on Browse Local Files...

3. A File Explorer window will open in the game folder. Navigate to _CommonRedist -> vcredist -> 2015 and run and install both of these files: vc_redist.x86.exe, vc_redist.x64.exe

4. Go up two folders in the hierarchy (so go back to _CommonRedist) and then navigate to DirectX -> Jun2010 and install DXSETUP.exe.

And that's it! You should now have all the necessary prerequisites to play the game.


For people still having issues, you can instead try the 2017 runtimes out. These runtimes replace the 2015 ones, so you don't lose anything by installing these while the 2015 are already installed.

The following are direct download links, open them in your browser:

* x86: https://go.microsoft.com/fwlink/?LinkId=746571
* x64: https://go.microsoft.com/fwlink/?LinkId=746572

I had the same problem of author of post. I it works for me

Oy, go to your Settings, click Apps, and check to see if you are missing one of the following:

Microsoft Visual Studio C++ 2010 (x86)
Microsoft Visual Studio C++ 2012 (x86)
Microsoft Visual Studio C++ 2013 (x86)
Microsoft Visual Studio C++ 2017 (x86)

if you are, go download it, it's not hard to find.

Edit: Nevermind. Christ, people these days give up way too easily...

I have deleted and reinstalled the game.

I have verified the integrity of the game files.

And just now, I tried to install Visual C++ Redistributable for Visual Studio 2017. Nothing has worked thus far. I'm beginning to think I bet on the wrong horse, here. I wanted to enjoy mods, but all this stuff plus...other controversy...isn't really worth the trouble...

The game depends on the x86 version of the Visual C++ 2015 Redistributable package:

It should also be found in the _CommonRedist folder of your Sonic Mania game.

None of these runtimes are used by Sonic Mania, which requires the 2015 x86 runtime.

2017 is an in-place replacement for 2015, so technically Sonic Mania can use either the 2015 or the 2017.

Now that I look it up, now I see. Guess I deserved that for never targeting above v120_xp.
In that case, I found this link from the Microsoft website: https://download.visualstudio.microsoft.com/download/pr/11100229/78c1e864d806e36f6035d80a0e80399e/VC_redist.x86.exe
That said, no runtimes earlier than 2015 are to the best of my knowledge relevant to Sonic Mania.
The only static dependencies (according to Dependency Walker) for Visual C++ are msvcp140.dll (C++ runtime) and vcruntime140.dll (C runtime).

Regardless, having them is better than not having them, as you won't have these missing DLL issues if you have them all installed, as many of these "missing" DLLS are in these older runtimes. So yes, they are relivent to Sonic Mania, as well as many other Games here on Steam.

Missing 2007-2013 runtimes won’t cause any issues for Sonic Mania players.

Games and applications that actually relies on those runtimes will install them during the installation of the game/application.

Unless it screws up, that's why you should just install it yourself, or at the very least have a copy to double check, sometimes the autorun of the MSVC included when steam begins to install it messes up, it's rare but it does happen from time to time (for me, that was Sonic Generations the first time I installed it) since then, I just install MSVC myself, less hassle that way, plus I'll know for sure if it installed the MSVC properly or not.
