Cannot Load C++ Project to Install Antilatency

[cgary009]

Hello. Not sure what category to put this question in. I’m at my whit’s end.

Background: I have Antilatency Camera Tracking mat and sensors for UE. Worked fine until I upgraded to Win 11 and Visual Studio 2022.

Now, when I try to open up a C++ project to install the Antilatency plugin, I rebuild and compile errors.

I’ve uninstalled UE, reinstalled, and tried other fixes where I have to change 15_1 to 15_2 in the ‘…target.cs’ file. Also changing code in WindowsPlatformComilerSetup.h. I’m getting no where and have been at this for 2 days.

Anyhow, have suggestions or anyone use Antilatency that can help?

Hi,

The issue seems to be you are using a compiler version newer than the one supported by UE 5.2 (At this point the default one will be too new).

Modifying the file WindowsPlatformComilerSetup.h to bump the version check is not advisable (If you changed it I recommend revering that change before trying the following fix).

The solution is to install the required version using the visual studio installer. Here is my answer with a screenshot example of a similar issue for UE 5.3

UE 5.3 Not packaging

As @RaPtOr_v9600 mentioned, you need to use the modiy option. What you need is leave the IDE version the same, but install different versions of some components. For the compiler, In the modify window you can go to the Individual components tab, and then search for MSVC 14.34 , and install the x86 version [image]

https://dev.epicgames.com/documentation/en-us/unreal-engine/unreal-engine-5.2-release-notes?application_version=5.2#developertools

The recommended version for UE 5.2 is

MSVC: 14.34.31933

I do appreciate the reply. I had updated Visual Studio to that unsupported version. It was unchecked after reinstalling but that didn’t fix my issues.

I’m still getting this error. I’ll try anything at this point other than paying for a new computer! Any other recommendations?

[Upgrade] Using backward-compatible include order. The latest version of UE has changed the order of includes, which may require code changes. The current setting is:
[Upgrade] IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_1
[Upgrade] Suppress this message by setting ‘IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_2;’ in MyProjectEditor.Target.cs.
[Upgrade] Alternatively you can set this to ‘EngineIncludeOrderVersion.Latest’ to always use the latest include order. This will potentially cause compile errors when integrating new versions of the engine.

You can try uninstalling address sanitizer by unchecking it in the visual studio installer, Individual components tab

I see in recent versions of UE we improved the check logic for address sanitizer availability, so this might be an issue in the old version.

If that doesn’t work, let me know.

Well, this computer is dedicated to a VFX side of my studio so it only needs to run UE (5.2 for Antilatency) and a couple other programs so I just did a clean install of Windows. Using the steps you sent and the not supported version of MSVC it worked just fine.

Going to connect the cameras tomorrow and take it all for a spin. Thank you for the help!
