So I've created my first game in UE4 (4.9.2 version) and want to publish it. But i really don't know how to determine lowest possible environment my game runs on.Also I am unsure what other files apart from actuall build I should redistribute. I am building game via file->package project->window.
To package a project for a specific platform, click on File > Package Project > [PlatformName] in the Editor's main menu: You will be presented with a dialog for selecting the target directory. If packaging completes successfully, this directory will then contain the packaged project.
1) How to determine minimum required DirectX version? 2) How to check what other dll's I need to include into installer (apart from actuall build)? For example will I need to install VC redistributable packages?

When you do this, Excel surrounds your array formula with braces — if you type the braces manually, your formula will be converted to a text string, and it won't work. Array functions are a really. Create an array formula that calculates a single result This type of array formula can simplify a worksheet model by replacing several different formulas with a single array formula. Click the cell in which you want to enter the array formula. How to use the array formula in Excel Mac? I understand that in windows, it will be to press CTRL + SHIFT + RETURN. And on Mac, it is supposed to be COMMAND + SHIFT + RETURN. This doesn't seem to work in Mac Excel 2016. After a bit of digging, it looks like the key combination for entering the array formula has changed from ⌘+RETURN to CTRL+SHIFT+RETURN. Array formula in excel for mac. My Excel install is version 15.27. I have seen people say that I need to hit CTRL+SHIFT+Enter or CMD+SHIFT+Enter but neither of these do anything at all.
If so then which ones? The same goes with directx. 3) How to determine minimal windows version? This is limited by directx compatibility right? How to set up a skype account. If my game runs on DirectX10 or higher then all OS versions with at least direct10 will be OK? 4) This may seem as stupid question but in which version 64 or 32 bit I should distribute my game? 32 is always better because anybody can run it right?
Thanks for Your answers;). @zehelvion Your point about the question having many questions in one is valid. But your editing made it worse. Before, the question(s) was(were) very well specified. Your review made it very generic, about 'lowest possible environment' - to the point that made me confuseda nd I had to check the past editions. I'm voting to rollback to its original state.
These comments here are enough to let the OP know he/she should try to better focus the question. Or answers might point they are going to focus on one or other points. – Nov 23 '15 at 7:43. First thing: as @ZEKE has suggested in the comments to your question, you should check: Also, in the end of the day, only experimenting can really give you final answers to that, as @Abstract-Sky has replied in the other answer. However, you can certainly have some pointers. Here, I will be answering to your original question, the one that brought multiple sub-questions - not to the edited version, because mentioning only 'lowest possible environment' becomes just too vague.
But, of course, I am only thoroughly answering to part of your sub-questions, because as @zehelvion has well put in the comments, it becomes hard to handle when multiple different stuff is mixed together in the same question. So: 1) How to determine minimum required DirectX version? By default, the minimum requirement of UE4 games as of 2014 was DirectX10, because the engine required SM4.0 GPU.
So, if you don't use any external libraries or plugins or functions that are specific to DirectX11 or 12, it's very likely that for your game DirectX10 will be also the baseline. So start by checking that. 2) How to check what other dll's I need to include into installer (apart from actuall build)? For example will I need to install VC redistributable packages?
If so then which ones? The same goes with directx.
That's impossible to answer without knowing in much more detail what have you used, implemented and included in your game. I think this one deserves a separate question with plenty of details about your game. 3) How to determine minimal windows version? This is limited by directx compatibility right?
If my game runs on DirectX10 or higher then all OS versions with at least direct10 will be OK? Not necessarily. Windows Vista had DirectX10 and still Epic never supported that OS officially.
So, it's unclear whether UE4 games would run on that without problems. I've read Epic staff mentioning that UE4 games could work under Vista, but that would be a case for empirical verification in a case-by-base basis. So if you want to aim Vista, there might be some hope. What is often said to be the minimal system for a game using UE4 is Windows 7 sp1.
However, again, if you installed or included any external library or plugins, you will have to double-check that all those also work back to Windows 7 sp1. But if your concern is to go even backward, for Windows XP compatibility, there might be also hope. Epic staff has mentioned in the past (see for instance this forum thread: ) that they were looking into giving compatibility to a version of OpenGL that would make it work even in Windows XP. In the UE4.2 release, they announced a preview of that compatibility: But by default, it's Windows 7 sp1 if nothing external from your game requires Windows 8 or 10. 4) This may seem as stupid question but in which version 64 or 32 bit I should distribute my game? 32 is always better because anybody can run it right?
