VS2019 support in Unreal 5.3

Development Programming & Scripting

Hi, I’m trying to understand whether Unreal 5.3 is intended to support Visual Studio 2019.

From the documentation at Setting Up Visual Studio Development Environment for C++ Projects in Unreal Engine | Unreal Engine 5.3 Documentation, it lists VS 2019 16.11.5 or later, however the release notes at Unreal Engine 5.3 Release Notes | Unreal Engine 5.3 Documentation state VS2022 17.4 or newer.

If I only have VC2019 installed (16.11.29), set up as described in the link above, on creating a new empty C++ project, I get the following error.

`Running C:/Program Files/Epic Games/UE_5.3/Engine/Build/BatchFiles/Build.bat -projectfiles -project=“C:/Users/—/Documents/Unreal Projects/MyProject2/MyProject2.uproject” -game -rocket -progress

Please update Visual Studio 2022 and ensure no configuration is forcing WindowsTargetRules.Compiler to VisualStudio2019. The current compiler version was detected as: 14.29.30151`

I’ve tried this in both the preview and the release versions with the same result. If I install VS2022, the project will be generated and build ok.

Is this likely to be an error with my setup, or with the documentation?

I have installed VS 2022, did the repair, and problem still persists.

I have the same problem, I can’t find a solution, I have updated the version of visual studio but it doesn’t work

So if I remove:

I get following message:

Ok, so after bit of drilling down, and huge help from ChatGPT, here is the problem and solution (or rather workaround).

In directory:
C:\Users\Admin\AppData\Roaming\Unreal Engine\UnrealBuildTool

There is a file that defines the build toolchain version (14.29.xxx or 14.37.xxx).
Deleting file is not working, it fails again.
However is you put in the file available version of toolchains on your computer, it works.
In directory:
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC

You will see the list of available toolchains, in my case it is:
image

Taking the bigger one: 14.37.32822 and putting this number into
BuildConfiguration.xml in C:\Users\Admin\AppData\Roaming\Unreal Engine\UnrealBuildTool

With the change, file looks like:

<?xml version="1.0" encoding="utf-8" ?> 
<Configuration xmlns="https://www.unrealengine.com/BuildConfiguration">
<WindowsPlatform>
    <CompilerVersion>14.37.32822</CompilerVersion>
</WindowsPlatform> </Configuration>

Everything started working as it should.
That said, I am still not sure why UBT do not use latest MSVC toolchain from the start.

Hi, thanks, I’ve just tried that again. I had tried setting the explicit version of VC (2019) installed in the BuildConfiguration.xml file previously, however the problem still persists for me.

The issue I have is that I currently can’t build against VS2022 on my build farm, as it currently only supports VS2019. I can build against 2022 locally, but am trying to determine if it’s possible to use VS2019 at all with this UE5.3 release as (some of) the documentation suggests it should be.

This issue was present in the previous 5.2 preview, but was resolved in the final release, but that does not seem to be the case this time.

I was getting the the same errors as you described above.
I have Visual Studio 2019 installed, as well as Visual Studio 2022.
Using UE 5.2, I have rebuilt the makefiles and recompiled my project using the newly installed Visual Studio 2022.
I have also made the above changers in BuildCOnfiguration.xml, which also matches the version I have installed - but when I go to convert the project to 5.3, it seems to keep trying to use Visual Studio 2019.

I have already regenerated the UE5.2 version of the project using VS 2022.
What causes UE 5.3 to keep trying to use use Visual Studio 2019 to build / convert the
project?

I get the following errors:

Project files could not be generated. Log output:

Obviously i don’t have the same problem, but here are few ideas where I would investigate next (advice is from ChatGPT):

  1. Problem with Project Path: The project path you have seems to contain spaces: D:/projects/UnrealProjects/MyMechGame5.2 5.3/MyMechGame.uproject. Spaces in file and directory names can sometimes cause issues.Solution: Rename your project folder to something without spaces. For example: D:/projects/UnrealProjects/MyMechGame5_2_5_3/MyMechGame.uproject.
  2. .NET 6.0 Support in Visual Studio 2019: The log clearly states that Visual Studio 2019 does not support .NET 6.0 C# projects.Solution: Upgrade to Visual Studio 2022, which supports .NET 6.0. This seems to be recommended by the log message as well.
  3. Unable to Find Valid 14.37.32822 C++ toolchain for VisualStudio2019 x64: The toolchain version you have installed seems to be 14.29.30133 (both for BuildTools and Community edition), but UE5 seems to be looking for 14.37.32822.Solution:
  • Ensure that you have all the necessary C++ development workloads installed through the Visual Studio installer.
  • Update your Visual Studio 2019 installation to ensure you have the latest toolchains. This can be done via the Visual Studio Installer.
  • As an alternative (and as a good future-proofing move), consider upgrading to Visual Studio 2022.
  1. Check the Log: Log file: C:\Users\cromp\AppData\Local\UnrealBuildTool\Log_GPF.txt. The specific details about the failure will be inside this log file.Solution: Open the specified log file to get more detailed information about the errors.

The path name is how UE 5.3 copies and renames the project when I open the 5.2 version of it. - it just tacks a space and 5.3 onto the end of it, so I don’t think that’s the problem or UE wouldn’t rename converted projects that way.

I have already upgraded to VS 2022, and have the 14.37.3282 build chain installed.
I also had recompiled the project under UE5.2 using VS2022, and can open the project into visual studio from the unreal editor.

I now also have 14.29.30133 installed too, but it seems to persist in using VS2019.
I have now also uninstalled VS2019, (which will be a headache for my other projects) so the only version of Visual Stuido I have installed is VS2022, yet it is still looking for VS2019 when doing the conversion for some reason:

Replying to my own question with the solution that finally worked for me:
I was still having problems with UE5.3 defaulting to VS 2019, which I think was causing the project conversions to fail.
To fix this I did the following:

  1. Created a new project using UE5.3.
  2. go to editor preferences->Source Code and set Source Code Editor to VS2022. I noted that it was previously set to VS2019, even though I don’t even have that installed any more.
  3. saved config to be the default config.
  4. Installed the VS extension again, using the steps here:
    Using the UnrealVS Extension for Unreal Engine C++ Projects | Unreal Engine 5.0 Documentation
  5. Exited and relaunched the new test project - now the Open Visual Studio Code menu option was available.
  6. opened the project in visual studio and tried to compile it. Visual Studio suggested adding additional build components for the project, which I did.
  7. Recompiled everything again in Visual Studio
  8. Exited the test project, closed UE5.3 and reopened it again, then selected my UE 5.2 project again, for copy and conversion. (it gave it a name with a space and 5.3 tacked on the end)
  9. After quite a while (several minutes) with the editor seemingly frozen, eventually the newly converted project opened and everything seems to work.
  10. posted the results here.

Thanks for suggestions and help. I was really struggling with this for 2 days.

Just chipping in.

I ran into the same issue.

Note the log file: C:\Users-–\AppData\Local\UnrealBuildTool\Log_GPF.txt

It lists the compiled versions it checks, which for me were:

Found Visual Studio toolchain: C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.29.30133 (Family=14.29.30133, FamilyRank=3, Version=14.29.30151, Is64Bit=True, ReleaseChannel=Latest, Architecture=x64, Error=False, Redist=C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Redist\MSVC\14.29.30133)

Found Visual Studio toolchain: C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.37.32822 (Family=14.37.32822, FamilyRank=4, Version=14.37.32822, Is64Bit=True, ReleaseChannel=Latest, Architecture=x64, Error=False, Redist=C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Redist\MSVC\14.36.32532)

In MicrosoftPlatformSDK.cs, where the logs are called, you’ll see that the toolchains are given a FamilyRank based on a PreferredVisualCppVersions list. This rank in my log is lower for the older versions, but the SelectToolChain() function sorts as such:

ToolChainInstallation? ToolChain = Preference(ToolChains.Where(x => x.Architecture == Architecture)
	.OrderByDescending(x => x.Error == null))
	.ThenByDescending(x => x.Is64Bit)
	.ThenBy(x => x.ReleaseChannel)
	.ThenBy(x => x.FamilyRank)
	.ThenByDescending(x => x.IsAutoSdk)
	.ThenByDescending(x => x.Version)
	.FirstOrDefault();

As FamilyRank is sorted ascending, it will prefer older versions instead of newer ones.

So my solution was to remove the older version of the toolchain from C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC

Hope this helps!

I had similar problems here. From my two versions of Visual Studio Unreal was always trying to take the older one. The solution was to explicitly set the compiler parameter (not only the compiler version parameter as it was suggested by SNINKOV):

  <WindowsPlatform>
      <Compiler>VisualStudio2022</Compiler>
      <CompilerVersion>14.37.32822</CompilerVersion>
  </WindowsPlatform>

There is no need to use VS2022 for UE 5.3 it will just slow your Machine as it is much heavier than vs2019, u can use just download MSVC 14.34 or 14.37 and .NET use simple lightweight IDE like Sublime Text

15

You have to, at least starting from 5.3.1.

16

Based on the following link it looks like the below should resolve that bit

<CompilerVersion>Latest</CompilerVersion>

Thank you very much for that, I really didn’t want to add the bloat of 2019 to my system and specifying the tag appears to have fixed it for me.

18

Thank you @SNINKOV and @oemintadiryi your solution saved me a lot of struggles.

19

these are the locations we need to check as per docs

  • Engine/Saved/UnrealBuildTool/BuildConfiguration.xml
  • <USER>/AppData/Roaming/Unreal Engine/UnrealBuildTool/BuildConfiguration.xml
  • My Documents/Unreal Engine/UnrealBuildTool/BuildConfiguration.xml
  • <PROJECT_DIRECTORY>/Saved/UnrealBuildTool/BuildConfiguration.xml

And also check

  • <PROJECT_DIRECTORY>/Config/DefaultEditor.ini
  • <PROJECT_DIRECTORY>/Config/DefaultEditorSettings.ini
    • [/Script/SourceCodeAccess.SourceCodeAccessSettings] PreferredAccessor=VisualStudio2022
  • <PROJECT_DIRECTORY>/Config/DefaultEngine.ini
    • [/Script/WindowsTargetPlatform.WindowsTargetSettings] Compiler=VisualStudio2022

HI SNINKOV. Thanks for digging into this. Looking at appdata\roaming\Unrel Engine] UnrealBuildTool, I see the xml file.

However, the only version folder in my MSVC folder it 14.29.30133. I updated my VS 2019 tonight to the latest version, but it just has this older version in there.

I looked at the modify option in VS installer and saw an ocean of options under compilers, but nothing with the version you show here.

How did you get that newer version?
